[media] bttv: remove g/s_audio since there is only one audio input
Note that the current driver does not implement enumaudio (so apps cannot
tell that audio inputs are present), it does not set V4L2_CAP_AUDIO, nor
does it set audioset when calling ENUM_INPUT. And G_AUDIO doesn't set the
stereo flag either. So these g/s_audio ioctls are quite pointless and
misleading. Especially since some surveillance boards do not have audio
at all.

[media] bttv: do not switch to the radio tuner unless it is accessed
Just opening the radio tuner should not cause a switch to the radio tuner.
Only after calling g/s_tuner or g/s_frequency should this happen.
This prevents audio being unmuted as soon as the driver is loaded because
some process opens /dev/radioX just to see what sort of node it is, which
switches on the radio tuner and unmutes audio.
This code can be improved further by actually keeping track of who owns the
tuner and returning -EBUSY if switching tuner modes will cause problems.
But for now just fix the annoying case where on boot the radio turns on
automatically.

If are there any code that switches off the frontend, via

[media] em28xx: add basic support for eeproms with 16 bit address width
Newer devices (em2874, em2884, em28174, em25xx, em27[6,7,8]x) use eeproms with
16 bit instead of 8 bit address width.
The used eeprom type depends on the chip type, which makes sure eeproms can't
be damaged.
This patch adds basic support for 16 bit eeproms only, which includes
- reading the content
- calculating the eeprom hash
- displaying the content
The eeprom content uses a different format, for which support will be added with
subsequent patches.
Tested with the "Hauppauge HVR-930C" and the "Speedlink VAD Laplace webcam"
(with additional experimental patches).

[media] em28xx: fix eeprom data endianess
The data is stored as little endian in the eeprom.
Hence the correct data types should be used and the data should be converted
to the machine endianess before using it.
The eeprom id (key) also isn't a 32 bit value but 4 separate bytes instead.

The current code uses only a single debug level and all debug messages are

Users expect debugging messages to become enabled for anything else than
debug level 0.

The em28xx driver has changed much, especially since kernel 3.8.
So it's time to bump the driver version.
Changes since kernel 3.8:
- converted the driver to videobuf2
- converted the driver to the v4l2-ctrl framework
- added USB bulk transfer support
- use USB bulk transfers by default for webcams (allows streaming from multiple devices at the same time)
- added image quality bridge controls: contrast, brightness, saturation, blue balance, red balance, sharpness
- removed dependency from module ir-kbd-i2c
- cleaned up the frame data processing code
- removed some unused/obsolete code
- made remote controls of devices with external (i2c) receiver/decoder work again
- fixed audio over USB for device "Terratec Cinergy 250"
- several v4l2 compliance fixes and improvements (including fixes for ioctls enabling/disabling)
- lots of further bug fixes and code improvements

Pull late ARM updates from Russell King:
"Here is the late set of ARM updates for this merge window; in here is:
- The ARM parts of the broadcast timer support, core parts merged
through tglx's tree. This was left over from the previous merge to
allow the dependency on tglx's tree to be resolved.
- A fix to the VFP code which shows up on Raspberry Pi's, as well as
fixing the fallout from a previous commit in this area.
- A number of smaller fixes scattered throughout the ARM tree"
