Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media 

Pull second set of media updates from Mauro Carvalho Chehab:

 - radio API: add support to work with radio frequency bands

 - new AM/FM radio drivers: radio-shark, radio-shark2

 - new Remote Controller USB driver: iguanair

 - conversion of several drivers to the v4l2 core control framework

 - new board additions at existing drivers

 - the remaining (and vast majority of the patches) are due to
   drivers/DocBook fixes/cleanups.

Who: Sylwester Nawrocki <sylvester.nawrocki@gmail.com>
----------------------------
What: Using V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT flags
to indicate a V4L2 memory-to-memory device capability
When: 3.8
Why: New drivers should use new V4L2_CAP_VIDEO_M2M capability flag
to indicate a V4L2 video memory-to-memory (M2M) device and
applications can now identify a M2M video device by checking
for V4L2_CAP_VIDEO_M2M, with VIDIOC_QUERYCAP ioctl. Using ORed
V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT flags for M2M
devices is ambiguous and may lead, for example, to identifying
a M2M device as a video capture or output device.
