The usual set of problems: the frequency isn't clamped to the frequency range,
no tuner index check and the frequency isn't initialized properly on module
load.

This driver now passes the tuner and frequency tests of v4l2-compliance.
It's the usual bugs: frequency wasn't clamped to the valid frequency range,
incorrect tuner capabilities and tuner fields not filled in, missing test
for invalid tuner index, no initial frequency and incorrect error handling.

Set the correct parent for v4l2_device_register and don't set the name
anymore (that's now deduced from the parent). Also remove an unnecessary
forward reference and fix two weird looking log messages.

The only reason for this header is to make sure that include
linux/time.h were added before uapi/*/dmx.h. Just push down the
time.h header on the few places where this is used, and drop
this new header.

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.

If we fail to set up the capture device we go through negative indexes and
badness happens. Add the missing test.
