Comment:
I feel like a hen raising ducks with this ALSA thing :-) I'll try to help
anyway.
How do you feel about the dummy states we have in
sound/soc/codecs/wm8753.c?
* Is it OK to have dummy states?
* Why do we have them on the first place?
We already know that Paul's patch avoids the crash but
there are more dummy states and another ALSA state that
works by using another mode. Thus I wonder if we have to:
1. Allow dummy states as they are now and just have some code to prevent
you from opening the device when a dummy state is selected so that we
don't crash.
or
2. Do something similar to what Paul did the patch he coded for all the
other states.
I'm worried that if we do (2) we will end up with different states that
do the same thing and create even more confusion.
Please advise...
