f3e94aa15d usb: core: don't try to reset_device() a port that got just disconnected
The USB hub driver's event handler contains a check to catch SuperSpeed
devices that transitioned into the SS.Inactive state and tries to fix
them with a reset. It decides whether to do a plain hub port reset or
call the usb_reset_device() function based on whether there was a device
attached to the port.

However, there are device/hub combinations (found with a JetFlash
Transcend mass storage stick (8564:1000) on the root hub of an Intel
LynxPoint PCH) which can transition to the SS.Inactive state on
disconnect (and stay there long enough for the host to notice). In this
case, above-mentioned reset check will call usb_reset_device() on the
stale device data structure. The kernel will send pointless LPM control
messages to the no longer connected device address and can even cause
several 5 second khubd stalls on some (buggy?) host controllers, before
finally accepting the device's fate amongst a flurry of error messages.

This patch makes the choice of reset dependent on the port status that
has just been read from the hub in addition to the existence of an
in-kernel data structure for the device, and only proceeds with the more
extensive reset if both are valid.

7d50195f6c usb: host: Faraday fotg210-hcd driver
FOTG210 is an OTG controller which can be configured as an
USB2.0 host. FOTG210 host is an ehci-like controller with
some differences. First, register layout of FOTG210 is
incompatible with EHCI. Furthermore, FOTG210 is lack of
siTDs which means iTDs are used for both HS and FS ISO
transfer.

02f00c4a91 USB: serial: pl2303: fix the upper baud rate limit check for type_0/1 chips
Fixes the following regression that has been introduced recently with
commit b2d6d98fc7:
With type_0 and type_1 chips
- all baud rates < 1228800 baud are rounded up to 1228800 baud
- the device silently runs at 9600 baud for all baud rates > 1228800
  baud

 "Okay as I warned, the qxl driver was running a bit free and loose with

  The first patch is a real fix to render the console correctly as the
  driver used to just drop irq renderering as too hard, this also fixes
  a sleeping while atomic warning.

  The other two patches are the big ugly ones that redo how the driver
  allocates objects and reserves them and makes things all work
  properly, I've tested this in a VM, and compared to the current code
  which hits a lockdep warning and the sleep while atomic warning before
  failing.

  So sorry this is coming in late, I should have tested qxl before

4e682bbd32 usb: limit OMAP related USB options to OMAP2PLUS platforms
commit 57f6ce072e ("usb: phy:
add a new driver for usb3 phy") added the new Kconfig option
OMAP_USB3, but it had no dependencies whatsoever, and hence
became available across all arch/platforms.

Which presumably caused this to show up in x86 randconfig:

    warning: (USB_MUSB_HDRC && OMAP_USB3) selects \
        OMAP_CONTROL_USB which has unmet direct \
        dependencies (USB_SUPPORT && ARCH_OMAP2PLUS)

Then commit 6992819feb ("usb: phy:
fix Kconfig warning") was added.  However, this just deleted the
ARCH_OMAP2PLUS dependency from OMAP_CONTROL_USB, further
compounding the problem by opening up OMAP_CONTROL_USB to
all arch/platforms as well.

Earlier it was suggested[1] that we revert the change of 6992819feb
to restore the dependency, and add a same ARCH_OMAP2PLUS dependency
to the new OMAP_USB3 entry.  However that was discouraged on the
grounds of people wanting the extra sanity compile testing on x86,
even though the driver could probably never be used there.

Now we have CONFIG_COMPILE_TEST, so developers who value the ability
to compile drivers on an architecture that it never can be used for
can have that, and people who want dependencies to shield them from
seeing options that aren't relevant to their platform get what they
want too.

Here we restore the dependency but couple it with COMPILE_TEST, in
order to achieve both of the above goals.

the usb_hcd_ep93xx_remove() into ohci_hcd_ep93xx_drv_remove(). As Alan
Stern pointed out, there is no reason for them to be separate.

Also, as Alan Stern suggested, eliminate the ep93xx_start_hc() and
ep93xx_stop_hc() routines and simply call clk_enable() and clk_disable()
directly. The extra level of redirection does not add any clarity.

fef36a7a31 ARM: SoC fixes for 3.11-rc
This is a largeish batch of fixes, mostly because I missed -rc2 due to
 travel/vacation. So in number these are a bit more than ideal unless
 you amortize them over two -rcs.
 
 Quick breakdown:
  - Defconfig updates
    - Making multi_v7_defconfig useful on more hardware to encourage
      single-image usage
    - Davinci and nomadik updates due to new code merged this merge window
  - Fixes for UART on Samsung platforms, both PM and clock-related
  - A handful of warning fixes from defconfig builds, including for
    max8925 backlight and pxamci (both with appropriate acks)
  - Exynos5440 fixes for LPAE configuration, PM
  - ...plus a bunch of other smaller changes all over the place
 
 I expect to switch to regressions-or-severe-bugs-only fixes from here
 on out.

 "This is a largeish batch of fixes, mostly because I missed -rc2 due to
  travel/vacation.  So in number these are a bit more than ideal unless
  you amortize them over two -rcs.

  Quick breakdown:
   - Defconfig updates
     - Making multi_v7_defconfig useful on more hardware to encourage
       single-image usage
     - Davinci and nomadik updates due to new code merged this merge
       window
   - Fixes for UART on Samsung platforms, both PM and clock-related
   - A handful of warning fixes from defconfig builds, including for
     max8925 backlight and pxamci (both with appropriate acks)
   - Exynos5440 fixes for LPAE configuration, PM
   - ...plus a bunch of other smaller changes all over the place

  I expect to switch to regressions-or-severe-bugs-only fixes from here

8e5c2b776a Revert "ACPI / video / i915: No ACPI backlight if firmware expects Windows 8"
We attempted to address a regression introduced by commit a57f7f9
(ACPICA: Add Windows8/Server2012 string for _OSI method.) after which
ACPI video backlight support doesn't work on a number of systems,
because the relevant AML methods in the ACPI tables in their BIOSes
become useless after the BIOS has been told that the OS is compatible
with Windows 8.  That problem is tracked by the bug entry at:

https://bugzilla.kernel.org/show_bug.cgi?id=51231

Commit 8c5bd7a (ACPI / video / i915: No ACPI backlight if firmware
expects Windows 8) introduced for this purpose essentially prevented
the ACPI backlight support from being used if the BIOS had been told
that the OS was compatible with Windows 8 and the i915 driver was
loaded, in which case the backlight would always be handled by i915.
Unfortunately, however, that turned out to cause problems with
backlight to appear on multiple systems with symptoms indicating that
i915 was unable to control the backlight on those systems as
expected.

For this reason, revert commit 8c5bd7a, but leave the function
acpi_video_backlight_quirks() introduced by it, because another
commit on top of it uses that function.

09d8091c02 tracing: Remove locking trace_types_lock from tracing_reset_all_online_cpus()
Commit a82274151a "tracing: Protect ftrace_trace_arrays list in trace_events.c"
added taking the trace_types_lock mutex in trace_events.c as there were
several locations that needed it for protection. Unfortunately, it also
encapsulated a call to tracing_reset_all_online_cpus() which also takes
the trace_types_lock, causing a deadlock.

This happens when a module has tracepoints and has been traced. When the
module is removed, the trace events module notifier will grab the
trace_types_lock, do a bunch of clean ups, and also clears the buffer
by calling tracing_reset_all_online_cpus. This doesn't happen often
which explains why it wasn't caught right away.

Commit a82274151a was marked for stable, which means this must be
sent to stable too.

Brown-paper-bag pull request here. The snb rc6 fix from the last pull
broke forcewake BIOS dirt cleanup, which with fixed. But that fix broke
the spinlock init sequence, which results in an ugly BUG when spinlock
debugging is enabled :( So I get to throw another patch at cc: stable to
fix up the mess ...

515c096720 mfd: max8925: fix dt code for backlight
The device-tree enablement for max8925 has several problems, but besides
the bindings being wrong (and not having seen review) there's also some
bad coding practices on how to fill in the platform_data from device tree.

I came across this since it causes a warning when compiling
mmp2_defconfig, and instead of doing the minimal fix to silence the
warning, I restructured the code a bit.

This silences the warning:
drivers/video/backlight/max8925_bl.c: In function 'max8925_backlight_probe':
drivers/video/backlight/max8925_bl.c:177:3: warning: statement with no effect [-Wunused-value]

Note that the bindings themselves need to be revisited too, but that will
affect more than just the backlight driver and is best done separately;
this just fixes the bad code for the backlight driver.

140983c283 USB: usb-skeleton.c: add retry for nonblocking read
Updated skel_read() in usb-skeleton.c. When there is no data in the
buffer, we would allow retry for both blocking and nonblocking cases.
Original logic give retry only for blocking case. Actually we can also
allow retry for nonblocking case. This will reuse the existing retry
logic and handle the return of -EAGAIN in one place. Also if the data to
be read is short and can be retrieved in quick time, we can also give a
chance for nonblocking case and may catch the data and copy it back to
userspace in one read() call too.

5dc50c357d usbfs: Allow printer class 'get_device_id' without needing to claim the intf
For certain (HP) printers the printer device_id does not only contain a
static part identifying the printer, but it also contains a dynamic part
giving printer status, ink level, etc.

To get to this info various userspace utilities need to be able to make a
printer class 'get_device_id' request without first claiming the interface
(as that is in use for the actual printer driver).

Since the printer class 'get_device_id' request does not change interface
settings in anyway, allowing this without claiming the interface should not
cause any issues.

An Embedded Host High-Speed Electrical Test (EHSET) test fixture is
used to initiate test modes on a host controller in order to perform
the high speed electrical testing procedure for USB-IF compliance.
When this test fixture is connected to a host, it can enumerate as
one of several selectable VID/PID pairs, each corresponding to one
of the following test modes:

* TEST_SE0_NAK
* TEST_J
* TEST_K
* TEST_PACKET
* HS_HOST_PORT_SUSPEND_RESUME
* SINGLE_STEP_GET_DEV_DESC
* SINGLE_STEP_SET_FEATURE

bInterval must be within the range 1 - 16
when running at High/Super speed, and within
the range 1 - 255 when running at Full/Low speed.

In order to catch drivers passing a too
large bInterval on Super/High speed scenarios
(thus overflowing urb->interval), let's clamp()
the argument to the allowed ranges.
