[PATCH 1/9] ASoC: codecs: Remove unused reg_cache fields from device structs
From: Lars-Peter Clausen
Date: Tue Dec 28 2010 - 15:40:35 EST
The multi-component patch(commit f0fba2ad1) moved the allocation of the
register cache from the driver to the ASoC core. Most drivers where adjusted to
this, but there are quite a few drivers left which now have an unused reg_cache field in
their private device struct.
This patch removes these unused fields.
