V4L/DVB (3663): Fix msp3400c wait time and better audio mode fallbacks
- The wait time until the first time the audio mode was detected was 1+5=6 seconds instead of just 1 second (wrong statement order). msp3400c specific bug. - Implemented audio mode fallback for msp3400c/d just like the msp3400g does automatically. E.g. fallback to stereo if no second language exists, etc. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
