V4L/DVB (13446): ivtv: Add more explicit detection of known IR devices for Hauppauge cards

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.

V4L/DVB (13445): cx18: Use per cx18 instance init data for ir-kbd-i2c instead of const data

initialization data to ir-kbd-i2c, since that module wants non-const data

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

V4L/DVB (13379): quickcam_messenger: possible buffer overflow while use strncat

In driver ./drivers/media/video/usbvideo/quickcam_messenger.c in line 91:

  91         usb_make_path(dev, cam->input_physname, sizeof(cam->input_physname));

After this line we use strncat:

  92         strncat(cam->input_physname, "/input0", sizeof(cam->input_physname));

where sizeof(cam->input_physname) returns length of cam->input_phisname
without length for null-symbol.  But this parameter must be - "maximum
numbers of bytes to copy", i.e.:
sizeof(cam->input_physname)-strlen(cam->input_physname)-1.

In this case, after call to usb_make_path the similar drivers use strlcat.

Like in: drivers/hid/usbhid/hid-core.c:
1152         usb_make_path(dev, hid->phys, sizeof(hid->phys));
1153         strlcat(hid->phys, "/input", sizeof(hid->phys));

On particularly weak signals, changing register 0xab after setting the

EQ lock).  So remove the write entirely, which seems to have had no adverse
effect in either of my ClearQAM environments (and in particular resolves the
customer's reported issue).

Also flip around the order of the amhum optimization and the interleave setup
to be consistent with the windows driver, which has the side-benefit of doing
them both in the same call (since the amhum optimization can only be done once
the interleave setup).

V4L/DVB (13330): s5h1409: properly handle QAM optimization after lock achieved

The sh51409 driver was only doing the QAM optimization a single time, and it
would only occur if you received a lock instantaneously after the tuning
request.  Restructure the code so that the optimization occurs once you reach
a signal lock.

Note that this depends on the caller polling for status, but we don't have
much choice at this point without an independent thread monitoring the lock
status.  Also, at this point pretty much every application polls for status
lock after doing the tune, so the likelihood of the optimization not occurring
in the real world is pretty low.

The state machine has also been reworked such that setting the interleave mode
is now a dependency of doing the QAM optimization.  Before both were mutually
exclusive, which was not consistent with the Windows driver.  We now have a
single state machine that controls both.

The changes as-is are only enabled for the HVR-1600.  Once the changes are
tested with some of the other boards, this change should be made generic and
the "_legacy" functions should be removed.
