b7a597d110 V4L/DVB (13925): gspca - main: Change the check of the USB video interface.
Some webcams have many interfaces with the same interface class, so the
previous interface check did not work.
The new code checks if the interface number is zero or the only one.

52a9d3ef00 V4L/DVB (13897): gspca - main: Check the interface class at probe time.
The USB video interface was checked as having the number zero, but
some webcams have other values. The test is now done on the interface
class which may be either 255 (vendor spec) or 0 (class per interface).

The gscpa core was not resubmitting URB's when the URB status was an error,
this means we will loose URB's (potentially all stopping the stream) in
case of sporadic USB issues. I've seen this with an Aiptek stv0680 based
PenCam connected through an USB 2.0 hub.

a511ba9476 V4L/DVB (13178): gspca: Add support for Winbond W9967CF and W9968CF camera's
This patch adds support to gspca for the Winbond W9967CF and W9968CF
camera's. This is mostly a port of the existing v4l1 driver to gspca
(making it v4l2). But this also features fixes to the bitbanging i2c code
(send a nack not an ack after reading the last byte of a transfer), which
gets rid of the weird errors which were being seen there, and of
the smbus_refresh() hack to get around these errors.

Also the vstart settings have been tweaked to work with different
frequency filter settings.

5a27578667 V4L/DVB (11263): gspca: Stop setting buffer type, and avoid memset in querycap
The v4l2-ioctl core checks the buffer type now by only allowing buffer
types for which the corresponding ->vidioc_try_fmt_xxx() methods are
defined.

This driver only defines ->vidioc_try_fmt_vid_cap() so only VIDEO_CAPTURE
buffers are allowed to be used with vidioc_g_parm.  Also,
->vidioc_enum_fmt_vid_cap() is only called for VIDEO_CAPTURE buffers.
There is no need to set the buffer type since it must already be the
correct value.

The struct which ->vidioc_querycap() is supposed to fill in is already
zeroed so it's not necessary to call memset on it.
