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:
 - a new jpeg codec driver for Samsung Exynos (jpeg-hw-exynos4)
 - a new dvb frontend for ds2103 chipset (m88ds2103)
 - a new sensor driver for Samsung S5K5BAF UXGA (s5k5baf)
 - new drivers for R-Car VSP1
 - a new radio driver: radio-raremono
 - a new tuner driver for ts2022 chipset (m88ts2022)
 - the analog part of em28xx is now a separate module that only
   load/runs if the device is not a pure digital TV device
 - added a staging driver for bcm2048 radio devices
 - the omap 2 video driver (omap24xx) was moved to staging.  This driver
   is for an old hardware and uses a deprecated Kernel internal API.  If
   nobody cares enough to fix it, it would be removed on a couple Kernel
   releases
 - the sn9c102 driver was moved to staging.  This driver was replaced by
   gspca, and disabled on some distros, as almost all devices are known
   to work properly with gspca.  It should be removed from kernel on a
   couple Kernel releases
 - lots of driver fixes, improvements and cleanups
