[alsa-devel] [PATCH 09/17] ASoC: multi-component - Wolfson WM87xx CODECs

11 Aug 2010

Moved Wolfson WM87xx CODECs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform driver
 o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
 o Removed all static codec pointers (drivers now support > 1 codec dev)
 o snd_soc_register_pcms() now done by core.
 o snd_soc_register_dai() folded into snd_soc_register_codec().
 o codec cache can now be malloc()ed by core.
Other required changes due to multi-component model :-
o wm8753: dai mode configuration now modifies private data to store mode.
