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:
 - removal of sn9c102.  This device driver was replaced a long time ago
   by gspca
 - solo6x10 and go7007 webcam drivers moved from staging into
   mainstream.  They were waiting for an API to allow setting the image
   detection matrix
 - SDR drivers moved from staging into mainstream: sdr-msi3101 (renamed
   as msi2500) and rtl2832
 - added SDR driver for airspy
 - added demux driver: si2165
 - rework at several RC subsystem, making the code for RC-5 SZ variant
   to be added at the standard RC5 decoder
 - added decoder for the XMP IR protocol
 - tuner driver moved from staging into mainstream: msi3101 (renamed as
   msi001)
 - added documentation for some additional SDR pixfmt
 - some device tree bindings documented
 - added support for exynos3250 at s5p-jpeg
 - remove the obsolete, unmaintained and broken mx1_camera driver
 - added support for remote controllers at au0828 driver
 - added a RC driver: sunxi-cir
 - several driver fixes, enhancements and cleanups.
