[0/6] media: uvcvideo: Hot fixes for top of next/uvc

Hi Laurent

Here are some fixes for your next branch. We have not sent yet the
patches to Mauro so I guess it is better to drop the broken patches
and their reverts from this set.

If it is too late the revert patches have the proper Fixes: tag

Thanks!

I deleted the wrong singed-off-by, This should say
Signed-off-by: Ricardo Ribalda <ribalda@chromium.org>

If I need to send a new version it will be fixed accordingly.
