Merge tag 'media/v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:
 "The part of patches for Kernel 4.5.  There's nothing really big here:

   - driver-specific headers for media devices were moved to separate
     directories, in order to make clear what headers belong to the core
     kABI and require documentation

   - Platform data for media drivers were moved from include/media to
     include/linux/platform_data/media

   - add a driver for cs3308 8-channel volume control, used on some
     high-end capture boards

   - lirc.h kAPI header were added at include/uapi/linux

   - Driver cleanups, new board additions and improvements"
