Subject: ASoC: wm8904: Fix GPIO and MICBIAS initialisation for regmap conversion
From: Mark Brown <[email protected]>
commit 433897f7408b556f7dfbb98c94deea02e634d2a7 upstream.
We no longer have a flat ASoC cache so can't peer directly into the array
any more but should instead use the register I/O functions to update the
cache.
