ASoC: ak4613: Enable cache usage to fix crashes on resume
[ Upstream commit dcd2d1f78664fdc75eadaaf65257834e24383d01 ]
During system resume:
kernel BUG at drivers/base/regmap/regcache.c:347!
...
PC is at regcache_sync+0x1c/0x128
LR is at ak4613_resume+0x28/0x34
The ak4613 driver is using a regmap cache sync to restore the
configuration of the chip on resume but does not actually define a
register cache which means that the resume is never going to work and we
trigger asserts in regmap. Fix this by enabling caching.
Based on commit d3030d11961a8c10 ("ASoC: ak4642: Enable cache usage to
fix crashes on resume") by Mark Brown <broonie@kernel.org>.
