Avoid legacy IR I2C probing for PVR-150, PVR-500, and PVR-350 cards. This
still probes, but restricts the possbile addresses probed per card.
Also removed legacy probe addresses for the KNC and PixelView cards which are
not supported by ivtv as far as I know.

Add explicit support for the AVerTV M116 for use with the ir-kbd-i2c module.
This also eases future support for other AVerMedia ivtv boards with the same

This avoids collisions of legacy IR controller probing with known I2C devices
in the card definitions in ivtv-cards.c. I2C driver modules for device listed
explicitly in a card definition should always take precedence over a probe
guessing where and IR controller may be.

Add a module parameter to adjust I2C SCL clock period per board. This allows

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.

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.

For whatever reason, the device structure pointer to
videobuf_queue_vmalloc_init is typed "void *", even though it's passed
right through to videobuf_queue_core_init(), which expects a struct
device pointer. The other videobuf implementations use struct device *;
I think vmalloc should too.

This initialization of the value of audio_mode is the one used if nothing
matches in the subsequent switch. The variable audio_mode is subsequently
assigned to constants such as TUNER_AUDIO_MONO and TUNER_AUDIO_STEREO.
TUNER_AUDIO_STEREO has the same value as V4L2_TUNER_MODE_STEREO, so it
would seem better to use that value here.
