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>

326 This is for apps that want to see an audio input
327 just to feel comfortable, as well as to test if
328 it can do stereo or sth. There is actually no guarantee
329 that the actual audio input cannot change behind the app's
330 back, but most applications should not mind that either.
331
332 Hopefully, mplayer people will work with us on this (this
333 whole mess is to support mplayer pvr://), or Hans will come
334 up with a more standard way to say "we have inputs but we
335 don 't want you to change them independent of video" which
336 will sort this mess.
