c1b283d55d [S390] tape: remove f_pos changes from read / write function.
The change to f_pos in the read / write method has no effect as the
value is controlled by the VFS layer, e.g. for vfs_read:

	loff_t pos = file_pos_read(file);
	ret = vfs_read(file, buf, count, &pos);
	file_pos_write(file, pos);

a6a5d73a56 [S390] zcrypt: special command support for cex3 exploitation
Support for special command is implemented in the AP Bus in the NQAP
function __ap_send. This is extended for a further parameter special.
When set, the special bit, in GR0 will be set. Therefor the ap_message
struct is extended for a further bit. Thus calling functions of
__ap_send can use the special parameter in ap_message to give to
__ap_send. Affected is in the first place ap_queue_message, which is
called by the actual card driver. The second part of this support is
that the card driver for the CEX3C needs to set this special bit, when
an according CPRB is sent to the driver.

f4ac1d0255 [S390] dasd: let device initialization wait for LCU setup
The first DASD that is set online for a specific logical control unit
has to do certain setup steps on the storage server to make full use
of it, for example it will enable PAV.
The features and characteristics reported by the storage server will
depend on this setup, so all other devices on the same LCU will need
to wait for the setup to be finished.

eb6e199bef [S390] dasd: improve error recovery for internal I/O
Most of the error conditions reported by a FICON storage server
indicate situations which can be recovered. Sometimes the host just
needs to retry an I/O request, but sometimes the recovery
is more complex and requires the device driver to wait, choose
a different path, etc.

The DASD device driver has a fully featured error recovery
for normal block layer I/O, but not for internal I/O request which
are for example used during the device bring up.
This can lead to situations where the IPL of a system fails because
DASD devices are not properly recognized.
This patch will extend the internal I/O handling to use the existing
error recovery procedures.

626350b63e [S390] dasd: enable prefix independent of pav support
The DASD device driver needs to explicitly enable the prefix command
on the storage server, before it can be used. Originally we enabled
this command along with others only if we wanted to support PAV.
However, today we require this command for other features like
High Performance FICON as well, so we need to always enable prefix.

22825ab769 [S390] dasd: support DIAG access for read-only devices
When a DASD device is used with the DIAG discipline, the DIAG
initialization will indicate success or error with a respective
return code. So far we have interpreted a return code of 4 as error,
but it actually means that the initialization was successful, but
the device is read-only. To allow read-only devices to be used with
DIAG we need to accept a return code of 4 as success.

Re-initialization of the DIAG access is also part of the DIAG error
recovery. If we find that the access mode of a device has been
changed from writable to read-only while the device was in use,
we print an error message.

d40f7b75a2 [S390] cio: dont unregister a busy device in ccw_device_set_offline
If we detect a busy subchannel after the driver's set_offline
callback returned in ccw_device_set_offline, the current behavior
is to unregister the device, which may lead to undesired
consequences. Change this to just quiesce the subchannel and go on
with the offline processing.

Note: This is no excuse for not fixing these drivers -
after the set_offline callback they should have no running IO!

c7b25a9e96 i2c: Drop probe, ignore and force module parameters
The legacy probe and force module parameters are obsolete now, the
same can be achieved using the new_device sysfs interface, which is
both more flexible and cheaper (it is implemented by i2c-core rather
than replicated in every driver module.)

The legacy ignore module parameters can be dropped as well. Ignoring
can be done by instantiating a "dummy" device at the problematic
address.

This is the first step of a huge cleanup to i2c-core's i2c_detect
function, i2c.h's I2C_CLIENT_INSMOD* macros, and all drivers that made

This patch (as1307) adds a small optimization to
__pm_request_resume().  If the device is currently being suspended,
there's no need to queue a work routine to resume it.  Setting the
deferred_resume flag will suffice.  (There's also a minor improvement
to the function's code layout: An unnecessary "else" is removed.)

Also, the patch clarifies the usage of the deferred_resume flag.  It
is meaningful only while a suspend is in progress, so it should be
cleared just before a suspend starts, not just after one ends.

The same loop to seek for a key were used on different places. Also,
no spinlock were protecting it to avoid the risk of replacing a keycode
while seeking for a new code.

This cleanup does:
	- create an unique function to seek for a code;
	- adds an spinlock to protect the table lookup;
	- remove some unused code;
	- simplifies to code to make it easier to understand.

Basically no change in behavior should be noticed after this patch.

It is easy to add support for all other RC5 IR's on em2880 boards, but
the scancode table needs to be re-generated. So, keep using the old

those tests, several bugs related to em2800 support were corrected.

for producing the usbsnoop dump, used to get the gpio's and allowing me
to remotelly access his machine and to the needed tests.

fb3de0398a em28xx: don't reduce scale to half size for em2800
Since em2800 can't support 720x480 / 720x576, the driver used to reduce
the scale to half the size on those chips. As the proper fix were
applied, reducing the maximum horizontal resolution to 640, this hack
can be removed.

0731160aca em28xx: don't load audio modules when AC97 is mis-detected
With em2800 hardware, AC97 hardware can be detected even when it doesn't
exist. If, after probing for AC97, the driver won't find a companion
chip, simply prevents the load of the audio modules.

1ca31892e3 em28xx: em2800 chips support max width of 640
Due to hardware limitation, em2800 chips can't work at resolutions
higher than 640x576, since the URB packet size is not enough.

The effect is that the image looses packages and shows a distortion

The encoder was not honoring the MDL size sent in DE_SET_MDL mailbox commands.
This change adjusts the size of the last buffer in an MDL, as reported to the
firmware, so that the encoder will send the exact amount of bytes we specify
per MDL transfer.  This eliminates tearing in YUV playback when using
non-default YUV buffer sizes.

22dce188ef V4L/DVB (13430): cx18: Fix YUV capture so that encoder passes a single frame per transfer
Fix YUV capture such that the encoder will pass one frame per transfer.  This
will allow the application to maintain frame alignment when a transfer from
the encoder is missed due to high system latency in service the CX23418 IRQ.

Also force YUV buffer sizes to be specified in multiples of 33.75 kB, the
smalled amount of buffer sizes need to store a complete set of HM12 4:2:0
macroblocks specifying 32 lines of the frame.  A full 60Hz/525 line
screen requires 15 * 33.75 kB per frame and a full 50Hz/625 line screen
requires 18 * 33.75 kB per frame so the default buffer size is 3 * 33.75 kB,
requiring exactly 5 or 6 buffers per MDL respectively.  The bytes needed per
frame and hence MDL need not be the bytes in an integer number of buffers.
However, if frame artifacts are seen with scaled screen sizes, the YUV buffer
size can be set 34 kB (33.75 kB) to get rid of the artifacts at the cost of more
copies between the kernel and userspace.

Alongside to the firedtv-1394.c backend for driver binding and I/O, the
firedtv-fw.c backend is added.  Depending on which of the two 1394
stacks is configured, one or the other or both backends will be built
into the firedtv driver.

This has been tested with a DVB-T and a DVB-C box on x86-64 and x86-32
together with a few different controllers (Agere FW323, a NEC chip, TI
TSB82AA2, TSB43AB22/A, VIA VT6306).
