Subject: [PATCH 0/2] media: v4l2: map UVC_CT_ROLL_ABSOLUTE_CONTROL

Hi,

Some new UVC cameras can report whether they are mounted in 'portrait 
mode'.

In order to userspace getting to know this, this series maps 
UVC_CT_ROLL_ABSOLUTE_CONTROL to V4L2_CID_ROLL_ABSOLUTE.

Tested with Logitech StreamCam and OBSBOT Tiny 2.
