struct video_device used to define a .hardware field. While
initialized on severl drivers, this field is never used inside V4L.
However, drivers using it need to include the old V4L1 header.
This seems to cause compilation troubles with some random configs.
Better just to remove it from all drivers.

Add two mute controls. One mutes everything, the other just mutes the analog
pass-through output.
Rename the existing volume control. The controls are now:
Playback Volume
Playback Switch
Capture Switch
These names might seem odd, but I believe they are more correct. The previous
"Capture Volume" control didn't actually effect the volume of the captured
audio. Instead it controls the volume of the analog pass-thought output. It
appears that pass-through controls like this are usually considered to be in
the playback direction, not capture. For example, "CAPTURE feedback Playback
Volume" is the name used for a control that appears to have the same effect in
the ca0106 driver. We only have one volume control, so we can omit the
"CAPTURE feedback" part.
If someone where to add PCM playback support to the driver, then this would be
the volume control.

Given that the author used an ß at all in a source file
indicates that the real name has in fact a 'ß' and not an 'ss',
which is commonly used as a substitute for 'ß' when limited to

The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.
The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.

CONFIG_VIDEO_BUF_DVB became CONFIG_VIDEOBUF_DVB.
But in these cases, it makes more sense to use CONFIG_VIDEO_SAA7134_DVB
or CONFIG_VIDEO_CX88_DVB_MODULE depending on the driver.
The reference in cx23885.h should just be removed, as the code there needs to
be included if DVB is on or off. I do not think you can even compile the
cx23885 driver without DVB. It's clearly just leftover from when the file was
obvious copied from the cx88 driver (which is not mentioned in the copyright
