The mem2mem_testdev allows multiple instances to be opened in parallel.
Source and destination queue data are being shared between all
instances, which can lead to kernel oops due to race conditions (most
likely to happen inside device_run()).

Attached patch fixes mentioned problem by storing queue data per device
context.

The (radio) audio out from the tuner (which can also demod FM radio) does not
seem to be hooked up to the msp3410 on this board in any way, so the only way
to get sound from the radio part is to make the msp3410 do the FM radio demod.

The msp3410 can handle this fine, but it is a bit weird compared to how it
is handled on other boards.

bttv_init_card2() sets btv->has_audio to a *default* value from the tvcards
array and then may update it by reading a card specific eeprom or gpio
detection.

After bttv_init_card2(), bttv_init_tuner() gets called, and it should clearly
use the updated, dynamic has_radio value from btv->has_radio, rather then
the const value in the tvcards array.

This fixes the radio not working on my Hauppauge WinTV.

Before this patch the owner field of the /dev/radio# device fops was set to
the snd-tea575x-tuner module itself. Meaning that the module which was using
it could be rmmod-ed while the device is open, and then BAD things happen.

I know, as I found out the hard way :)

Note that there is no need to also somehow increase the refcount of the
snd-tea575x-tuner module itself, since any drivers using it will have
symbolic references to it.

Yuck. The VIDIOC_(TRY_)DECODER_CMD ioctls already had ioctl numbers 96 and 97,
and after merging the timings API I forgot to continue numbering from 98. So
now we have two ioctls with number 96 and two with 97.

With the new table-driver ioctl handling in v4l2-ioctl.c it is essential that
each ioctl has its own unique number, so let's fix this quickly for 3.5.
