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"
