Subject[PATCH 4.14 196/237] ASoC: cs42l52: Correct TLV for Bypass Volume
Date
From: Charles Keepax <ckeepax@opensource.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.
