Subject: ASoC: wm8962: Turn on regcache_cache_only before disabling regulator
From: Nicolin Chen <b42378@xxxxxxxxxxxxx>
commit 50bfcf2df2fadf77e143d6099150e6fa7ef4d78c upstream.
It's safer to turn on regcache_cache_only before disabling regulator since
the driver will turn off the regcache_cache_only after enabling regulator.
If we remain cache_only false, some command like 'amixer cset' would get
failure if being run before wm8962_resume().
