From: Hans de Goede hdegoede@redhat.com Date: Sun, 18 Feb 2018 23:01:44 +0100 Subject: ASoC: rt5651: Fix regcache sync errors on resume
From: Hans de Goede hdegoede@redhat.com
commit 2d30e9494f1ea320aaaad0cff9ddd92c87eac355 upstream.
The ALC5651 does not like multi-write accesses, avoid them. This fixes:
rt5651 i2c-10EC5651:00: Unable to sync registers 0x27-0x28. -121
Errors on resume (and all registers after the registers in the error not being synced).
