2591530204 usb: serial: fix memory leak in generic driver
Fix a regression introduced by commit
715b1dc01f ("USB: usb_debug,
usb_generic_serial: implement multi urb write").

URB transfer buffer was never freed when using multi-urb writes. 
Currently the only driver enabling multi-urb writes is usb_debug.

4e092d110f USB: ftdi_sio: sort PID/VID entries in new ftdi_sio_ids.h header
This is a (almost) sort-only patch to sort FTDI device
product ID definitions in new ftdi_sio_ids.h header.

Advantage is that new device ID submissions will now have a specific (sorted)
position - less future merge conflicts.

Compile-tested, based on _current_ mainline git.
Minor checkpatch.pl warnings were eliminated whereever it made sense,
very minor text changes.

c1e13f2567 kfifo: move out spinlock
Move the pointer to the spinlock out of struct kfifo.  Most users in

4546548789 kfifo: move struct kfifo in place
This is a new generic kernel FIFO implementation.

The current kernel fifo API is not very widely used, because it has to
many constrains.  Only 17 files in the current 2.6.31-rc5 used it.
FIFO's are like list's a very basic thing and a kfifo API which handles
the most use case would save a lot of development time and memory
resources.

I think this are the reasons why kfifo is not in use:

 - The API is to simple, important functions are missing
 - A fifo can be only allocated dynamically
 - There is a requirement of a spinlock whether you need it or not
 - There is no support for data records inside a fifo

So I decided to extend the kfifo in a more generic way without blowing up
the API to much.  The new API has the following benefits:

 - Generic usage: For kernel internal use and/or device driver.
 - Provide an API for the most use case.
 - Slim API: The whole API provides 25 functions.
 - Linux style habit.
 - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros
 - Direct copy_to_user from the fifo and copy_from_user into the fifo.
 - The kfifo itself is an in place member of the using data structure, this save an
   indirection access and does not waste the kernel allocator.
 - Lockless access: if only one reader and one writer is active on the fifo,
   which is the common use case, no additional locking is necessary.
 - Remove spinlock - give the user the freedom of choice what kind of locking to use if
   one is required.
 - Ability to handle records. Three type of records are supported:
   - Variable length records between 0-255 bytes, with a record size
     field of 1 bytes.
   - Variable length records between 0-65535 bytes, with a record size
     field of 2 bytes.
   - Fixed size records, which no record size field.
 - Preserve memory resource.
 - Performance!
 - Easy to use!

This patch:

Since most users want to have the kfifo as part of another object,
reorganize the code to allow including struct kfifo in another data
structure.  This requires changing the kfifo_alloc and kfifo_init
prototypes so that we pass an existing kfifo pointer into them.  This
patch changes the implementation and all existing users.

3a2b808e95 USB: serial: sierra driver memory reduction
This patch deals with reducing the memory footprint for sierra driver.
This optimization is aimed for embedded software customers.

Some sierra modems can expose upwards of 7 USB interfaces, each possibly
offering different services. In general, interfaces used for the
exchange of wireless data require much higher throughput, hence require
more memory (i.e. more URBs) than lower performance interfaces. URBs
used for the IN direction are pre-allocated by the driver and this patch
introduces a way to configure the number of IN URBs allocated on a
per-interface basis. Interfaces with lower throughput requirements
receive fewer URBs, thereby reducing the RAM memory consumed by the
driver.

NOTE1: This driver has always pre-allocated URBs for the IN direction.

NOTE2: The number of URBs pre-allocated for the low-performance
interfaces has already been extensively tested in previous versions of
this driver.

We also added the capability to log function calls by adding DEBUG flag.
Please note that  this flag is commented out because this is the default
state
for it.

Original discussion:

or
http://marc.info/?l=linux-usb&m=125553790714133&w=2

9a68e39d4a broke carrier handling so that a
cp210x setup which needed the carrier lines set up (non CLOCAL) which did
not make a call which set the termios bits left the lines down even if
CLOCAL was not asserted.

Fix this not by reverting but by adding the proper dtr_rts and
carrier_raised methods. This both sets the modem lines properly and also
implements the correct blocking semantics for the port as required by
POSIX.

This patch presents fixes for the autosuspend feature implementation in
sierra usb serial driver in  functions sierra_open(), sierra_close() and
stop_read_write_urbs().

The patch "sierra_close() must resume the device before it notifies it
of a closure" submitted by Oliver Neukum on Wed, October 14 has been
merged as fix in sierra_close() function.

The bug fix  in sierra_open() function restores the autopm interface
state on error condition.

3c77d5137d USB: serial: sierra driver send_setup() autopm fix
This patch presents a fix for the autosuspend feature implementation in
sierra usb serial driver for function sierra_send_setup().  Because it
is possible to call sierra_send_setup() before sierra_open() or after
sierra_close() we added a get/put interface activity to assure that the
usb control can happen even when the device is autosuspended.

f278a2f7bb tty: Fix regressions caused by commit b50989dc
The following commit made console open fails while booting:

	commit b50989dc44
	Author: Alan Cox <alan@linux.intel.com>
	Date:   Sat Sep 19 13:13:22 2009 -0700

	tty: make the kref destructor occur asynchronously

Due to tty release routines run in a workqueue now, error like the
following will be reported while booting:

INIT open /dev/console Input/output error

It also causes hibernation regression to appear as reported at
http://bugzilla.kernel.org/show_bug.cgi?id=14229

The reason is that now there's latency issue with closing, but when
we open a "closing not finished" tty, -EIO will be returned.

Fix it as per the following Alan's suggestion:

  Fun but it's actually not a bug and the fix is wrong in itself as
  the port may be closing but not yet being destructed, in which case
  it seems to do the wrong thing.  Opening a tty that is closing (and
  could be closing for long periods) is supposed to return -EIO.

  I suspect a better way to deal with this and keep the old console
  timing is to split tty->shutdown into two functions.

  tty->shutdown() - called synchronously just before we dump the tty
  onto the waitqueue for destruction

  tty->cleanup() - called when the destructor runs.

  We would then do the shutdown part which can occur in IRQ context
  fine, before queueing the rest of the release (from tty->magic = 0
  ...  the end) to occur asynchronously

  The USB update in -next would then need a call like

       if (tty->cleanup)
               tty->cleanup(tty);

  at the top of the async function and the USB shutdown to be split
  between shutdown and cleanup as the USB resource cleanup and final
  tidy cannot occur synchronously as it needs to sleep.

  In other words the logic becomes

       final kref put
               make object unfindable

       async
               clean it up

25b8286805 USB-serial: pl2303: fix baud rate handling in case of unsupported values
According to the datasheets, the PL2303 supports a set of 25 baudrates.
The baudrate is set as a 4 byte value directly.

During my experiments with device 067b:2303 (PL2303X), I noticed that
 - the bridge-controller always uses 9600 baud if invalid/unsupported baud rate
   values are set
 - the baud rate value returned by usb_control_msg(..., GET_LINE_REQUEST, ...)
   does not reflect the actually used baudrate. Always the last set value is
   returned, even if it was invalid and not used by the controller.

This patch fixes the following issues with the current code:
1.) make sure that only supported baudrates are set (are there any buggy
    chip revisions out there which don't "like" other values... ?).
2.) always set the baudrate to the next nearest supported baudrate.
3.) applications can now read back the resulting baudrate properly, because
    tty_encode_baud_rate(...) is now fed with the actually used baudrate.

8e8dce0650 USB: use kfifo to buffer usb-generic serial writes
When do_output_char() attempts to write a carriage return/line feed sequence,
it first checks to see how much buffer room is available. If there are at least
two characters free, it will write the carriage return/line feed with two calls
to tty_put_char(). It calls the tty_operation functions write() for devices that
don't support the tty_operations function put_char(). If the USB generic serial
device's write URB is not in use, it will return the buffer size when asked how
much room is available. The write() of the carriage return will cause it to mark
the write URB busy, so the subsequent write() of the line feed will be ignored.

This patch uses the kfifo infrastructure to implement a write FIFO that
accurately returns the amount of space available in the buffer.

7bd032dc27 USB serial: update the console driver
This patch (as1292) modifies the USB serial console driver, to make it
compatible with the recent changes to the USB serial core.  The most
important change is that serial->disc_mutex now has to be unlocked
following a successful call to usb_serial_get_by_index().

Other less notable changes include:

	Use the requested port number instead of port 0 always.

	Prevent the serial device from being autosuspended.

	Use the ASYNCB_INITIALIZED flag bit to indicate when the
	port hardware has been initialized.

In spite of these changes, there's no question that the USB serial
console code is still a big hack.

320348c8d5 usb-serial: straighten out serial_open
This patch (as1291) removes a bunch of code from serial_open(), things
that were rendered unnecessary by earlier patches.  A missing spinlock
is added to protect port->port.count, which needs to be incremented
even if the open fails but not if the tty has gotten a hangup.  The
test for whether the hardware has been initialized, based on the use
count, is replaced by a more transparent test of the
ASYNCB_INITIALIZED bit in the port flags.

cc56cd0157 usb-serial: acquire references when a new tty is installed
This patch (as1287) makes serial_install() be reponsible for acquiring
references to the usb_serial structure and the driver module when a
tty is first used.  This is more sensible than having serial_open() do
it, because a tty can be opened many times whereas it is installed
only once, when it is created.  (Not to mention that these actions are
reversed when the tty is released, not when it is closed.)  Finally,
it is at install time that the TTY core takes its own reference to the
usb_serial module, so it is only fitting that we should act the same
way in regard to the lower-level serial driver.

8bc2c1b2da usb-serial: change logic of serial lookups
This patch (as1286) changes usb_serial_get_by_index().  Now the
routine will check whether the serial device has been disconnected; if
it has then the return value will be NULL.  If the device hasn't been
disconnected then the routine will return with serial->disc_mutex
held, so that the caller can use the structure without fear of racing
against driver unloads.

This permits the scope of table_mutex in destroy_serial() to be
reduced.  Instead of protecting the entire function, it suffices to
protect the part that actually uses serial_table[], i.e., the call to
return_serial().  There's no longer any danger of the refcount being
incremented after it reaches 0 (which was the reason for having the
large scope previously), because it can't reach 0 until the serial
device has been disconnected.

Also, the patch makes serial_install() check that serial is non-NULL
before attempting to use it.

41bd34ddd7 usb-serial: change referencing of port and serial structures
This patch (as1284) changes the referencing of the usb_serial and
usb_serial_port structures in usb-serial.c.  It's not feasible to make
the port structures keep a reference to the serial structure, because
the ports need to remain in existence when serial is released -- quite
a few of the drivers expect this.  Consequently taking a reference
to the port when the device file is open is insufficient; such a
reference would not pin serial.

To fix this, we now take a reference to serial when the device file is
opened.  The final put_device() for the ports occurs in
destroy_serial(), so that the ports will last as long as they are
needed.

The patch initializes all the port devices, including those in the
unused "fake" ports.  This makes the code more uniform because they
can all be released in the same way.  The error handling code in
usb_serial_probe() is much simplified by this approach; instead of
freeing everything by hand we can use a single usb_serial_put() call.

Also simplified is the port-release mechanism.  Instead of being two
separate routines, port_release() and port_free() can be combined into
one.

The USB layer uses tty_hangup to deal with unplugs of the physical hardware
(analogous to loss of carrier) and then frees the resources. However the
tty_hangup is asynchronous. As the hangup can sleep we can use tty_vhangup
which is the non async version to avoid freeing resources too early.

9d498beafc USB: aten uc2324 is really a moschip 7840
I've opened up the case, and the chips in the ATEN UC2324 are:

Moschip
MCS7840CV-AA
69507-6B1
0650
(USB to 4-port serial)

(logo with AF kerned together)  0748  
24BC02  
SINGLP
(unknown 8-pin chip)

(logo looks like 3 or Z in circle)
ZT3243LEEA    0752
B7A16420.T
(4 chips, so this will be RS232 line driver)
(Probably equivalent of Sipex SP3243)

So the ATEN 2324 (aten2011.c driver), is definitely the Moschip 7840,
and should use the mos7840.c driver.  I expect you will remove the
aten2011.c driver from the staging area.

From the aten2011.c source code, the device ID for the UC2322 (2 port
serial) is 0x7820, just like the Moschip evaluation board.  This value
should be added to the device id table of mos7840.c.

Here's a patch that adds these devices to the driver.

This patch (as1264) removes a bunch of unnecessary and erroneous stuff
from the option USB-serial driver.  Clearly there's no need to verify
that the device pointer stored in the URBs is right or to store the
same pointer over again.  After all, the pointer can't change once it
has been set up.

There's also no need to call usb_clear_halt for the IN endpoint
multiple times -- in fact, doing so is an error since every time after
the first there will be active URBs queued for that endpoint.  Since
the Clear-Halts don't appear to be needed at all, the patch simply
removes them.

This patch (as1263) fixes a mixup that occurred when conflicting
patches for the sierra driver were merged incorrectly.  The former
sierra_shutdown routine should have been become sierra_release, not
sierra_disconnect.

The symptom this fixes is an oops when the device file is closed after
a Sierra device has been unplugged (Bugzilla #13675).

Add A-Link 3GU device id 1e0e:9200 into option driver. The device
has 4 interfaces, of which 1 is handled by storage and the other 3
by option driver.

The device appears first as CD-only 1e0e:f000 device and must be
switched to 1e0e:9200 mode either by using "eject CD" or
usb_modeswitch.

For the record, the device does not work with generic usbserial
driver (usb disconnect when sending the ATDT command).

b760dac290 USB: ftdi: support NDI devices
It enhances the driver for FTDI-based USB serial adapters to recognize and
support Northern Digital Inc (NDI) measurement equipment. NDI has been
providing this patch for various kernel flavors for several years and we would
like to see these changes built in to the driver so that our equipement works
without the need for customers to patch the kernel themselves.

The patch makes small modifications to 2 files: ./drivers/usb/serial/ftdi_sio.c
and ./drivers/usb/serial/ftdi_sio.h. It accomplishes 3 things:

1. Define the VID and PIDs to allow the driver to recognize the NDI devices.
2. Map the 19200 baud rate setting to our higher baud rate of 1.2Mb
   We would have chosen to map 38400 to the higher rate, similar to what
   several other vendors have done, but some of our legacy customers actually
   use 38400, therefore we remap 19200 to the higher rate.
3. We set the default transmit latency in the FTDI chip to 1ms for our devices.
   Our devices are typically polled at 60Hz and the default ftdi latency
   seriously affects turn-around time and results in missed data frames. We
   have created a modprobe option that allows this setting to be increased.
   This has proven necessary particularly in some virtualized environments.

6e40612101 USB: console: Fix regression in usb console on kernel boot
The commit 335f8514f2 introduced a
regression which stopped usb consoles from working correctly as a
kernel boot console as well as interactive login device.

The addition of the serial_close() which in turn calls
tty_port_close_start() will change the reference count of port.count
and warn about it.  The usb console code had previously incremented
the port.count to indicate it was making use of the device as a
console and the forced change causes a double open on the usb device
which leads to a non obvious kernel oops later on when the tty is
freed.

To fix the problem instead make use of port->console to track if the
port is in fact an active console port to avoid double initialization
of the usb serial device.  The port.count is incremented and
decremented only with in the scope of usb_console_setup() for the
purpose of the low level driver initialization.

As an example, open fails with a non-existing device, when probe has

This patch (as1254) splits up the shutdown method of usb_serial_driver
into a disconnect and a release method.

The problem is that the usb-serial core was calling shutdown during
disconnect handling, but drivers didn't expect it to be called until
after all the open file references had been closed.  The result was an
oops when the close method tried to use memory that had been
deallocated by shutdown.

568d422e9c USB: usb_serial: only allow sysrq on a console port
The only time a sysrq should get processed is if the attached device
is a console.  This is intended to protect sysrq execution on a host
connected with a terminal program.

Here is the problem scenario:

host A <-- rs232 link --> host B

Host A is using mincom and a usb pl2303 device to connect to host b
which is a linux system with a usb pl2303 device acting as the serial
console.  When host B is rebooted the pl2303 emits random junk
characters on reset.  These character sequences contain serial break
signals most of the time and when translated to a sysrq have caused
host A to get random processes killed, reboots or power down.

It is true that in this setup with this patch host B might still have
the same problem as host A if you reboot host A.  In most cases host A
is a development host which seldom gets rebooted, and you could turn
off sysrq temporarily on host B if you need to reboot host A.

98fcb5f781 USB: serial: usb_debug,usb_generic_serial: implement sysrq and serial break
The usb_debug driver was modified to implement serial break handling
by using a "magic" data packet comprised of the sequence:

       0x00 0xff 0x01 0xfe   0x00 0xfe 0x01 0xff

When the tty layer requests a serial break the usb_debug driver sends
the magic packet.  On the receiving side the magic packet is thrown
away or a sysrq is activated depending on what kernel .config options
have been set.

The generic serial driver was modified as well as the usb serial
headers to generically implement sysrq processing in the same way the
non usb uart based drivers implement the sysrq handling.  This will
allow other usb serial devices to implement sysrq handling as desired.

The new usb serial functions are named similarly and implemented
similarly to the uart functions as follows:

usb_serial_handle_break <-> uart_handle_break
usb_serial_handle_sysrq_char <-> uart_handle_sysrq_char

715b1dc01f USB: usb_debug, usb_generic_serial: implement multi urb write
The usb_debug driver, when used as the console, will always fail to
insert the carriage return and new line sequence as well as randomly
drop console output.  This is a result of only having the single
write_urb and that the tty layer will have a lock that prevents the
processing of the back to back urb requests.

The solution is to allow more than one urb to be outstanding and have
a slightly deeper transmit queue.  The idea and some code is borrowed
from the ftdi_sio usb driver.

The generic usb serial driver was modified so as to allow the classic
method of 1 write urb, or a multi write urb scheme with N allowed
outstanding urbs where N is controlled by max_in_flight_urbs.  When
max_in_flight_urbs in a "struct usb_serial_driver" is non zero the
multi write urb scheme will be used.

The size of 4000 was selected for the usb_debug driver so that the
driver lowers possibility of losing the queued console messages during
the kernel startup.

4db2299da2 sierra: driver interface blacklisting
Interface blacklisting is necessary for non-serial interfaces that are handled
by a different driver. The interface blacklisting is implemented in sierra
driver per device. Each device in need of a blacklist has a static information
array kept in the driver. This array contains the interface numbers that are
blacklisted. The pointer for each blacklist array and the length
of that blacklist are 'bundled' in data structure sierra_iface_info. A pointer
to this information is set in id_table when the device is added to the id_table.

The following is summary of changes we have made to sierra.c driver in
this patch dealing with interface blacklisting support:
- Added data structure sierra_iface_info and function is_blacklisted()
to support blacklisting
- Modified sierra_probe() to handle blacklisted interfaces accordingly
- Improved comments in id_table
- Added new device in id_table with blacklist interface support

b9a44bc19f sierra: driver urb handling improvements
[Folded from eight patches into one as the original set according to the
 author "All of the patches need to be applied to obtain a working product"
 so keeping them split seems unhelpful

 Merge fixes done versus other conflicting changes and moved the
 spin_lock_init from open to setup time -- Alan]

Summary of the changes and code re-organization in this patch:

- The memory for urbs is allocated and urbs are submitted only for the active
  interfaces (instead of pre-allocating these for all interfaces). This will
  save memory especially in the case of using composite devices.
- The code has been re-organized and functionality has been extracted from
  sierra_startup(), sierra_shutdown(), sierra_open(), sierra_close() and added
  in helper functions sierra_release_urb(), sierra_stop_rx_urbs(),
  sierra_submit_rx_urbs() and sierra_setup_urb()

- Added function sierra_release_urb() to free an urb and its transfer
buffer.
- Removed unecessary include file reference and comment.
- Added function sierra_stop_rx_urbs() that takes care of the release of
receive and interrupt urbs. This function is to be called by sierra_close()
whenever an interface is de-activated.
- Added new function sierra_submit_rx_urbs() that handles the submission of
receive urbs and interrupt urbs (if any) during the interface activation.
This function is to be called by sierra_open(). Added a second parameter to
pass the memory allocation (as suggested by Oliver Neukum) so that this
function can be used in post_reset() and resume().
- Added new function sierra_setup_urb() that contains the functionality to
allocate an urb, fill bulk urb using the supplied memory allocation flag
and release urb upon error. Added parameter so that the caller pass the
memory allocation flag for flexibility.
- Moved sierra_close() before sierra_open() to resolve dependencies
introduced by the code reorganization.
- Modified sierra_close() to call sierra_stop_rx_urbs() and
sierra_release_urb() functions added in previous patch.
- Modified sierra_open() to call sierra_setup_urb() and sierra_submit_rx_urbs()
functions; note urbs are allocated and submitted for each activated interface.
- Modified sierra_startup() so that allocation of urbs happens whenever an
interface is activated (urb allocation is moved to sierra_open()).
- Modified sierra_shutdown() so that urbs are freed whenever an interface is
de-activated (urb freeing moved to sierra_close() as shown in previous patch
from the series)
- Removed unecessary data structure from sierra_port_private_data
- Suppress an entry in logs by not re-submitting an urb when usb_submit_urb()
returns -EPERM, as this shows that usb_kill_urb() is running (as suggested by
Oliver Neukum)

0a3c8549ea usb-serial: fix crash when sub-driver updates firmware
This patch (as1244) fixes a crash in usb-serial that occurs when a
sub-driver returns a positive value from its attach method, indicating
that new firmware was loaded and the device will disconnect and
reconnect.  The usb-serial core then skips the step of registering the
port devices; when the disconnect occurs, the attempt to unregister
the ports fails dramatically.

This problem shows up with Keyspan devices and it might affect others
as well.

When the attach method returns a positive value, the patch sets
num_ports to 0.  This tells usb_serial_disconnect() not to try
unregistering any of the ports; instead they are cleaned up by
destroy_serial().

80193195f8 Fix oops on close of hot-unplugged FTDI serial converter
Commit c45d6320 ("fix reference counting of ftdi_private") stopped
ftdi_sio_port_remove() from directly freeing the port-private data, with
the intention if the port was still open, it would be freed when
ftdi_close() is eventually called and releases the last refcount on the
structure.

That's all very well, but ftdi_sio_port_remove() still contains a call
to usb_set_serial_port_data(port, NULL) -- so by the time we get to
ftdi_close() for the port which was unplugged, it _still_ oopses on
dereferencing that NULL pointer, as it did before (and does in 2.6.29).

The fix is just not to clear the private data in ftdi_sio_port_remove().
Then the refcount is properly reduced to zero when the final kref_put()
happens in ftdi_close().

Remove a bogus comment too, while we're at it. And stop doing things
inside "if (priv)" -- it must _always_ be there.

Based loosely on an earlier patch by Daniel Mack, and suggestions by
Alan Stern.

2d93148ab6 USB: serial: fix lifetime and locking problems
This patch (as1229) fixes a few lifetime and locking problems in the
usb-serial driver.  The main symptom is that an invalid kevent is
created when the serial device is unplugged while a connection is
active.

	Ports should be unregistered when device is disconnected,
	not when the parent usb_serial structure is deallocated.

	Each open file should hold a reference to the corresponding
	port structure, and the reference should be released when
	the file is closed.

	serial->disc_mutex should be acquired in serial_open(), to
	resolve the classic race between open and disconnect.

	serial_close() doesn't need to hold both serial->disc_mutex
	and port->mutex at the same time.

	Release the subdriver's module reference only after releasing
	all the other references, in case one of the release routines
	needs to invoke some code in the subdriver module.

	Replace a call to flush_scheduled_work() (which is prone to
	deadlocks) with cancel_work_sync().  Also, add a call to
	cancel_work_sync() in the disconnect routine.

	Reduce the scope of serial->disc_mutex in serial_disconnect().
	The only place it really needs to protect is where the
	"disconnected" flag is set.

This fixes the bug reported in

Fixup of Werner Cornelius patch to the ch341 USB-serial driver, which adds:
- support all baudrates, not just a hard-coded set
- support for controlling DTR, RTS and CTS

Features still missing:
- character length other than 8 bits
- parity settings
- break control

I adapted his patch for the new usb_serial API introduced in 2.6.25-git8 by
Alan Cox on 22 July 2008. Non-compliance to the new API was a reason for
refusing a similar patch from Tollef Fog Heen.

Usage example by Tollef Fog Heen :
        TEMPer USB thermometer <http://err.no/src/TEMPer.c>

based on a patch by:

	From: Tollef Fog Heen <tfheen@err.no>

	* Implement support for all baud rates rather than just a hard
	  coded set.
	* Make it possible to control status and control lines
	* Grab a bunch of #defines from FreeBSD to reduce the number of
	  magic numbers in the file

d2ad67b3fa USB: Fix cp2101 USB serial device driver termios functions for console use
This is really a follow up to the modifications Alan Cox made for commit
95da310e66 to pass a tty_struct to various
interface functions, which broke the serial configuration (termios) functions
when the device is being used as a console. These changes restore the
configuration to proper functioning both as a tty and as a console.  As Alan
notes in that commit, these changes will need to be tweaked when we have
a proper console abstraction.

1ded7ea47b USB: ch341 serial: fix port number changed after resume
This patch fixes the following bug:
	.plug ch341 usb serial port into a hub port;
	.ch341 driver bound to the device and /dev/ttyUSB0 comes
	.open /dev/ttyUSB0 by minicom and we can use the serial successfully
	.suspend the ch341 usb serial device(such as: echo suspend > power/level)
	.resume the ch341 usb serial device (such as: echo on > power/level)
	.new port /dev/ttyUSB1 comes ,and the original /dev/ttyUSB0 still exists,
but is no longer usable by minicom

The patch adds suspend and resume callback to ch341 usb driver to prevent it
from unbinding during suspend. The /dev/ttyUSB0 is not released until being
closed, so /dev/ttyUSB1 comes after resume, and the original /dev/ttyUSB0 is
no longer usable by minicom. It is really a mess for a minicom user.

This patch also adds the reset_resume callback to make it usable after resuming
from STR or hibernation, for generally STR or hibernation will make the vbus
of root-hub lost.

Finally enable the driver's supports_autosuspend, for the device is in working
order with it.

331879fd6f USB: serial: refuse to open recently removed USB Serial devices
A USB-serial converter device is plugged into a system, and a process
opens it's device node.  If the device is physically removed whilst the
process still has its device node open, then other processes can
sucessfully open the now non-existent device's node.  I would expect
that open() on a device that has been physically removed should return
ENODEV.

This is manifesting itself with getty on my system.  I do the following:
1.  set up inittab to spawn getty on ttyUSB0, eg:
    T1:23:respawn:/sbin/getty -L ttyUSB0 115200 vt100
2.  Plug in USB-serial converter cable
3.  Wait for a login prompt on a terminal program attached to the serial
    cable
4.  Login
5.  Pull the USB-serial converter cable from the box
6.  getty doesn't realise that ttyUSB0 no longer exists as /dev/ttyUSB0
    can still be opened.
7.  Re-insert the USB-serial converter cable
8.  You should no longer get a login prompt over the serial cable, as
    the the USB-serial cable now shows up as /dev/ttyUSB1, and getty is
    trying to talk to /dev/ttyUSB0.

The attached patch will cause open("/dev/ttyUSB0", O_RDONLY) to return
ENODEV after the USB-serial converter has been pulled.  The patch was
created against 2.6.28.1.  I can supply it against something else if
needs be.  It is fairly simple, so should be OK.

I am using a pl2303 device, although I don't think that makes any
difference.

2e0fe70968 USB: drivers: use USB API functions rather than constants
This set of patches introduces calls to the following set of functions:

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)

In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:

USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

This patch fixed it for me, but I don't know if the original device id was
also correct and the new ID should be added instead of replacing the
old one.

To modify the data value and length in the function of
usb_stor_huawei_e220_init in initializers.c That's because based on the USB
standard, while sending SET_FETURE_D to the device, it requires the
corresponding data to be zero, and its sending length also must be zero.  In
our old solution, it can be compatible with our WCDMA data card devices, but
can not support our CDMA data card devices.  But in this new solution, it can
be compatible with all of our data card devices.

4ad6de0b3f usb: fix pl2303 initialization
This patch removes the private check for the termios_initialized for
the pl2303 usb driver.  It forced the baud to 9600 on the first call
to pl2303_set_termios()

Based on the tty changes in the 2.6.27 kernel, the termios passed to
the *_set_termios functions is always populated the first time.

This means there is no need to privately initialize the settings the
first time, and doing so will not allow the use of the kernel
parameter "console=ttyUSB0,115200" as an example.

7aef709bf6 Fix oti6858 debug level
For some reason the oti6858 driver undefines and redefines the dbg
macro. This makes it spew debugging messages at KERN_INFO instead of
KERN_DEBUG.

This patch removes the undef and define making the driver log like every
other USB serial driver.
