Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media into next

Pull media updates from Mauro Carvalho Chehab:
 "This contains:
   - a new frontend/tuner driver set for si2168 and sa2157
   - Videobuf 2 core now supports DVB too
   - A new gspca sub-driver (dtcs033)
   - saa7134 is now converted to use videobuf2
   - add support for 4K timings
   - several other driver fixes and improvements

  PS.  This pull request is shorter than usual, partly because I have
  some other patches on topic branches that I'll be sending you later
  this week"
