[alsa-devel] [PATCHv2] ASoC: Fix wrong data type access in a few codec drivers
Commit fafd217 ("ASoC: Store a list of widgets in a DAPM mux/mixer kcontrol") changed the control private data type that is passed to snd_soc_cnew when creating dapm mixer and mux controls. Commit did not update a few codec drivers that are using their own put callbacks and thus are accessing a wrong data type.

This version looks good to me. I guess that means:
Acked-by: Stephen Warren swarren@nvidia.com
... although I figure my Tested-by is probably enough.
Thanks for fixing my bugs!
