[media] cx88: convert to vb2
As usual, this patch is very large due to the fact that half a vb2 conversion
isn't possible. And since this affects blackbird, alsa, core, dvb, vbi and
video the changes are all over.
What made this more difficult was the peculiar way the risc program was setup.
The driver allowed for running out of buffers in which case the DMA would stop
and restart when the next buffer was queued. There was also a complicated
timeout system for when buffers weren't filled. This was replaced by a much
simpler scheme where there is always one buffer around and the DMA will just
cycle that buffer until a new buffer is queued. In that case the previous
buffer will be chained to the new buffer. An interrupt is generated at the
start of the new buffer telling the driver that the previous buffer can be
passed on to userspace.
Much simpler and more robust.

The prefered fix would be to convert the whole IR code to use the kernel IR
infrastructure (which wasn't available at the time this driver had been created).
Until anyone who still has this old hardware steps up an does the conversion,
fix it by not calling the symbol_request calls if the driver is compiled in
without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE).
Due to the IR related pointers beeing NULL by default, IR support will then be disabled.
The downside of this solution is, that it will no longer be possible to
compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in.
Please note that this patch has NOT been tested with all possible cases.
I don't have the hardware and could only verify that it fixes the reported
bug.

[media] s5p-mfc: Don't crash the kernel if the watchdog kicks in
If the software watchdog kicks in, the watchdog worker is not synchronized
with hardware interrupts and does not block other instances. It's possible
for it to clear the hw_lock, making other instances trigger a BUG() on
hw_lock checks. Since it's not fatal to clear the hw_lock to zero twice,
just WARN in those cases for now. We should not explode, as firmware will
return errors as needed for other instances after it's reloaded, or they
will time out.
A clean fix should involve killing other instances when watchdog kicks in,
but requires a major redesign of locking in the driver.

Timestamp i of a previously decoded buffer was overwritten for some

In most cases this wrong indexing might not have been noticed except
for a one frame delay in frame presentation. For H.264 streams though
that require reordering of frames for presentation, it caused a slightly

This patch adds JPEG encoding and decoding support for CODA7541,
using the BIT processor. Separate JPEG encoder and decoder video
devices are created due to different streaming behaviour and
different supported pixel formats.
The hardware can not change subsampling on the fly, but encode
and decode 4:2:2 subsampled JPEG images from and into this format.
The CODA7541 JPEG decoder uses the bitstream buffer and thus can run
without new buffers queued if there is a buffer in the bitstream.
Since there is no standard way to store the colorspace used in
JPEGs, and to make v4l2-compliance happy, the JPEG format always
reports V4L2_COLORSPACE_JPEG.
