    Subject[PATCH 1/6] ASoC: Remove unused "control_data" field of struct wm8904_priv
    From
    Date
    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.
