[PATCH 3.11 024/131] ASoC: max98090: sync regcache on entering STANDBY

From: Luis Henriques
Date: Wed Mar 05 2014 - 10:26:26 EST


3.11.10.6 -stable review patch. If anyone has any objections, please let me know.

------------------

From: Dylan Reid <dgreid@xxxxxxxxxxxx>

commit c42c8922c46d33ed769e99618bdfba06866a0c72 upstream.

Sync regcache when entering STANDBY from OFF. ON isn't entered with
OFF as the current state, so the registers were not being re-synced
after suspend/resume.

The 98088 and 98095 already call regcache_sync from STANDBY.
