[RFC PATCH 2/3] ASoC: soc-topology: enable use of multiple control types

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

 



Modify the kcontrol creation and delete functions to operate based on
individual kcontrol type. Previously all kcontrols in a widget we're
assumed to have the same type.
