Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- some V4L2 API updates needed by embedded devices
- DVB API extensions for ATSC-MH delivery system, used in US for mobile
TV
- new tuners for fc0011/0012/0013 and tua9001
- a new dvb driver for af9033/9035
- a new ATSC-MH frontend (lg2160)
- new remote controller keymaps
- Removal of a few legacy webcam driver that got replaced by gspca on
several kernel versions ago
- a new driver for Exynos 4/5 webcams(s5pp fimc-lite)
- a new webcam sensor driver (smiapp)
- a new video input driver for embedded (sta2x1xx)
- several improvements, fixes, cleanups, etc inside the drivers.
Manually fix up conflicts due to err() -> dev_err() conversion in
drivers/staging/media/easycap/easycap_main.c
