Tobias Lorenz 2f94fc465a V4L/DVB (10533): fix LED status output
This patch closes one of my todos that was since long on my list.
Some people reported clicks and glitches in the audio stream,
correlated to the LED color changing cycle.
Thanks to Rick Bronson <rick@efn.org>.

Hans Verkuil bec43661b1 V4L/DVB (10135): v4l2: introduce v4l2_file_operations.
Introduce a struct v4l2_file_operations for v4l2 drivers.

Remove the unnecessary inode argument.

Move compat32 handling (and llseek) into the v4l2-dev core: this is now
handled in the v4l2 core and no longer in the drivers themselves.

Note that this changeset reverts an earlier patch that changed the return
type of__video_ioctl2 from int to long. This change will be reinstated
later in a much improved version.

Tobias Lorenz 617f53336c V4L/DVB (9218): si470x: removement of get/set input/audio
This patch removes the unnecessary get/set input/audio functions.

The reason is, that the V4L2 specification says, that if input or audio
cannot be switched anyway, the functions doesn't need to be implemented.

I've tested the new driver with all current radio programs in
Debian/testing and found no problems with that.

In my opinion, the driver is much cleaner by removing these unnecessary
functions.

Hans Verkuil a399810ca6 V4L/DVB (8482): videodev: move all ioctl callbacks to a new v4l2_ioctl_ops struct
All ioctl callbacks are now stored in a new v4l2_ioctl_ops struct. Drivers fill in
a const struct v4l2_ioctl_ops and video_device just contains a const pointer to it.

This ensures a clean separation between the const ops struct and the non-const
video_device struct.
