[PATCH 6.1 33/71] ASoC: codecs: wcd938x: fix headphones volume controls

From: Sasha Levin
Date: Wed Mar 13 2024 - 13:11:38 EST


From: Johan Hovold <johan+linaro@xxxxxxxxxx>

[ Upstream commit 4d0e8bdfa4a57099dc7230952a460903f2e2f8de ]

The lowest headphones volume setting does not mute so the leave the TLV
mute flag unset.

This is specifically needed to let the sound server use the lowest gain
setting.
