V4L/DVB: ov7670: Don't use SMBUS I/O
Contrary to my earlier belief, the ov7670 is not actually an SMBUS device,
though it will pretend to be one if it's in a good mood. Unfortunately,
it's rarely in a good mood, especially on the XO 1.5. So use low-level i2c
I/O instead.

V4L/DVB: videodev2: introduce a common control for chroma gain
Introduce a new control for modifying the chroma gain. This allows for user
intervention in abnormal signal conditions cases where the decoder's chroma
AGC cannot compensate and the value needs to be adjusted manually.
This patch enables the anti-alias filter, which was originally enabled for
the saa7113, but the saa7115_init_misc was trampling the value. Without this
patch, there would be visible vertical bands in the chroma.
Thanks to Andy Walls for helping test this change against other ivtv products.
V4L/DVB: em28xx: rework buffer pointer tracking for offset to start of video
Rework the logic for tracking the amount of data copied to the VBI buffer, to
address problem found where the video lines are several bytes shifted to the
right (and the leading pixels in the first line rendered are garbage). This
would occur because the copy function would advance the pointer when detecting
headers, but the caller would not adjust the length actually copied.
It turns up we can reduce the starting line for the active area, which results
in more data being captured when under PAL (while the full VBI capture window
still stays properly encoded).
Increase the packets per URB count from 40 to 64. I suspect that whoever was
looking at the usbsnoop captures saw "0x40" packets and mistook it for "40".
As a result of this change, I can see a 25% reduction in the number of
interrupts generated via powertop.

V4L/DVB: drivers/media/video: move dereference after NULL test
In quickcam_messenger.c, if the NULL test on uvd is needed, then the
dereference should be after the NULL test.
In vpif_display.c, std_info is initialized to the address of a structure

In saa7134-alsa.c, the function is only called from one place, where the

should be kept, then card should be initialized after it.
