| Subject: ASoC: rt5631: Fix regcache sync errors on resume |
| |
| From: Maxim Schwalm <maxim.schwalm@gmail.com> |
| |
| [ 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. |
