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.

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.

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!

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.

Modifies the IR table for HVR-950 to use the newer Hauppauge RC5 table,

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

Also, the 7bits tables are still used on other drivers, so this small

The s2250-board i2c module was converted to use v4l2-i2c-drv.h in
preparation for its subdev conversion. This change prevented the
s2250-loader from being initialized within the same module due to
the module_init and module_exit function definitions in v4l2-i2c-drv.h.
Therefore, s2250-loader is now its own module, and the header for
exporting s2250-loader functions is no longer needed.
The s2250 i2c module name was "2220-board" in some places, and was

Since em2800 can't support 720x480 / 720x576, the driver used to reduce

Due to hardware limitation, em2800 chips can't work at resolutions
higher than 640x576, since the URB packet size is not enough.

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.
