Subject: [PATCH 0/3] media: uvcvideo: Support partial control reads and
 minor changes

Some cameras do not return all the bytes requested from a control
if it can fit in less bytes. Eg: returning 0xab instead of 0x00ab.
Support these devices.

Also, now that we are at it, improve uvc_query_ctrl().
