[PATCH 4/6] ASoC: Remove unused "control_data" field of structwm8978_priv

From: Axel Lin
Date: Tue Sep 27 2011 - 08:43:34 EST


The control_data field is used to initialize the codec's control_data field,
but since this is also done by the snd-soc-cache core, the redundant
assignment can be removed and the field can be dropped.
