- add device_caps support
- fix bus_info
- fix numerous tuner-related problems due to incorrect tests
and setting v4l2_tuner fields to wrong values.
- remove (audio) input support from the radio: it doesn't belong
there. This also fixed a nasty issue where opening the radio
would set dev->input to 5 for no good reason. This was never
set back to a valid TV input after closing the radio device,
thus leaving it at 5 which is out of bounds of the vinput
card array.

On systems where it cannot be assured that enough continous memory is available
all the time it can be very useful to only allocate the memory once when it is
needed the first time. Afterwards the initially allocated memory will be
reused, so it is ensured that the memory will stay available until the driver
is unloaded.

Convert a nonnegative error return code to a negative one, as returned
elsewhere in the function.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
{ ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
when != &ret
*if(...)
{
... when != ret = e2
when forall
return ret;
}
// </smpl>

Write-only ioctls should have a const argument in the ioctl op.
Do this conversion for vidioc_s_audio.
Adding const for write-only ioctls was decided during the 2012 Media Workshop.
