[PATCH v3 11/19] audio: deprecate -soundhw pcspk

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add deprecation message to the audio init function.

Factor out audio initialization and call that from
both audio init and realize, so setting audiodev via
-global is enough to properly initialize pcspk.
