[alsa-devel] [PATCH v3] ASoC: cs42l56: Fix new value argument in snd_soc_update_bits calls

[Axel Lin]

The new value argument needs proper shift to match the mask bit fields.

Signed-off-by: Axel Lin <axel.lin at ingics.com>
---
v3: Define CS42L56_MUTE_ALL as 0xff, so all the mask bits will be set.
v2: Address Brian's comment in v1.
