Subject: [PATCH AUTOSEL 4.19 04/18] ASoC: cs42l52: Correct TLV for Bypass Volume
From: Charles Keepax <ckeepax@...nsource.cirrus.com>
[ Upstream commit 91e90c712fade0b69cdff7cc6512f6099bd18ae5 ]
The Bypass Volume is accidentally using a -6dB minimum TLV rather than
the correct -60dB minimum. Add a new TLV to correct this.
