3.16.7-ckt23 -stable review patch. If anyone has any objections, please let me know.

From: Mans Rullgard <mans@xxxxxxxxx>
commit 1ea5998afe903384ddc16391d4c023cd4c867bea upstream.
Attempting to use this codec driver triggers a BUG() in regcache_sync()
since no cache type is set. The register map of this device is fairly
small and has few holes so a flat cache is suitable.
