[PATCH 1/6] ASoC: Remove unused "control_data" field of struct ak4671_priv

[PATCH 1/6] ASoC: Remove unused "control_data" field of struct ak4671_priv

[Axel Lin]

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.

Although Mark, it would have been nice if you had given me a chance to test this
change before applying the patch.

With this sort of repetitive change by Axel I'm often not really going
to register which particular dirver he's fixing in a given patch - he's
generally very good and one of the advantages of keeping all the drivers
consistent is that it's easy to deploy subsystem wide changes.
