gspca: Stop setting buffer type, and avoid memset in querycap
From: Trent Piepho <xyzzy@speakeasy.org>
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.
Priority: normal
