    Subject[PATCH 4.19 184/234] 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.
