[PATCH 0/4] Some fix patches for uvc gadget function

[Xu Yang <xu.yang_2@nxp.com>]

Recenly when test uvc gadget function I find some YUYV pixel format
720p and 1080p stream can't output normally. However, small resulution
and MJPEG format stream works fine. The first patch#1 is to fix the issue.

Patch#2 and #3 are small fix or improvement.

For patch#4: it's a workaround for a long-term issue in videobuf2. With
it, many device can work well and not solely based on the SG allocation
method.
