V4L/DVB (5094): Pvrusb2: Introduce fake audio input selection
This should allow mplayer pvr:// to start. The trick is that no matter what actual input we use under this "fake" one, it will be able to do stereo :-) Signed-off-by: Pantelis Koukousoulas <pakt223@freemail.gr> Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
