| 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). |
