We can benefit from knowing that the file system no longer cares about
the contents of certain sectors, by throwing them away immediately and
then never having to garbage collect them, and using the extra free
space to make our operations more efficient. Do so.

It was a patch for 2.6.28 where the BKL was pushed down from v4l core to

The atmel-mci driver sometimes fails data transfers like this:
mmcblk0: error -5 transferring data
end_request: I/O error, dev mmcblk0, sector 2749769
end_request: I/O error, dev mmcblk0, sector 2749777
It turns out that this might be caused by the BLKR register (which
contains the block size and the number of blocks being transfered) being
initialized too late. This patch moves the initialization of BLKR so
that it contains the correct value before the block transfer command is
sent.
This error is difficult to reproduce, but if you insert a long delay
(mdelay(10) or thereabouts) between the calls to atmci_start_command()
and atmci_submit_data(), all transfers seem to fail without this patch,
while I haven't seen any failures with this patch.

The Swarm IDE driver uses a release method which is defined in the driver
itself thus potentially oopsable. The simple fix would be to just leak
the device but this patch goes the full length and moves the entire
handling of the platform device in the platform code and retains only
the platform driver code in drivers/ide/mips/swarm.c.

Apparently, 'xcount' being 0 does not mean 0 bytes for TRM290; it means 4 bytes,
judging from the code immediately preceding this check. So, we must never try
to "split" the PRD for TRM290.
This is probably never hit anyway -- with the DMA buffers aligned to at least
512 bytes and ATAPI DMA not being used for non block I/O commands...

Correct audio routing for composite/s-video
Add DVB-T detection.
This patch uses the eeprom hash method for detection as the vendor/product
ids are also used for the DIGIVOX_AD. This may be a clone of the same
product. Explanatory text has been added prior to the hask look-up in
anticipation that it may help others.
The following has been tested to work:

There is a buffer overflow in drivers/media/video/uvc/uvc_ctrl.c:
INFO: 0xf2c5ce08-0xf2c5ce0b. First byte 0xa1 instead of 0xcc
INFO: Allocated in uvc_query_v4l2_ctrl+0x3c/0x239 [uvcvideo] age=13 cpu=1 pid=4975
...
A fixed size 8-byte buffer is allocated, and a variable size field is read
into it; there is no particular bound on the size of the field (it is
dependent on hardware and configuration) and it can overflow [also
verified by inserting printk's.]
The patch attempts to size the buffer to the correctly.

Different backends have different input busses (saa7146, flexcop).
To reflect that a config-option to the s5h1420-driver was added which makes
the output mode selectable.
Furthermore the s5h1420-driver is now doing the same i2c-method as it was done
before adding support for other i2c-users.
This patch needs to go into the current release of the kernel, as this driver
is currently broken.

dvb_dmx_swfilter_packet, dvb_dmx_swfilter_packets, dvb_dmx_swfilter and
dvb_dmx_swfilter_204 may be called from both interrupt and process
context. Therefore they need to be protected by spin_lock_irqsave()
instead of spin_lock().
