| |
3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Brown <broonie@opensource.wolfsonmicro.com>
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.
