V4L/DVB (9327): v4l: use video_device.num instead of minor in video%d
Hans Verkuil [Sun, 19 Oct 2008 21:54:26 +0000 (18:54 -0300)]
The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now
independent of the minor number. So instead of using the minor field
of the video_device struct one has to use the num field: this always
contains the kernel number of the device node.

I forgot about this when I did the v4l2 core change, so this patch
converts all drivers that use it in one go. Luckily the change is
trivial.
