    Subject[PATCH 4.14 007/109] ASoC: rt5651: Fix regcache sync errors on resume
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    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).
