Pull media updates from Mauro Carvalho Chehab:
- V4L2 API additions to better support JPEG compression control
- media API additions to properly support MPEG decoders
- V4L2 API additions for image crop/scaling
- a few other V4L2 API DocBook fixes/improvements
- two new DVB frontend drivers: m88rs2000 and rtl2830
- two new DVB drivers: az6007 and rtl28xxu
- a framework for ISA drivers, that removed lots of common code found
at the ISA radio drivers
- a new FM transmitter driver (radio-keene)
- a GPIO-based IR receiver driver
- a new sensor driver: mt9m032
