Merge tag 'media/v4.1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:
 "Three driver fixes:

   - fix for omap4, fixing a regression due to a subsystem API that got
     removed for 4.1 (commit efde2346);

   - fix for one of the formats supported by Marvel ccic driver;

   - fix rcar_vin driver that, when stopping abnormally, the driver
     can't return from wait_for_completion"

  [media] v4l: omap4iss: Replace outdated OMAP4 control pad API with syscon
