ASoC: rt5631: Fix regcache sync errors on resume
[ Upstream commit c71f78a662611fe2c67f3155da19b0eff0f29762 ]
The ALC5631 does not like multi-write accesses, avoid them. This fixes:
rt5631 4-001a: Unable to sync registers 0x3a-0x3c. -121
errors on resume from suspend (and all registers after the registers in
the error not being synced).
Inspired by commit 2d30e9494f1e ("ASoC: rt5651: Fix regcache sync errors
on resume") from Hans de Geode, which fixed the same errors on ALC5651.
