Subject: ASoC: Don't go through cache when applying WM5100 rev A updates
From: Mark Brown <[email protected]>
commit 495174a8ffbaa0d15153d855cf206cdc46d51cf4 upstream.
These are all to either uncached registers or fixes to register defaults,
in the former case the cache won't do anything and in the latter case
we're fixing things so the cache sync will do the right thing.
