Subject: [PATCH 4/6] ASoC: cs42l52: Correct TLV for Bypass Volume
Date:   Thu, 2 Jun 2022 17:21:17 +0100
Message-ID: <20220602162119.3393857-5-ckeepax@opensource.cirrus.com>

The Bypass Volume is accidentally using a -6dB minimum TLV rather than
the correct -60dB minimum. Add a new TLV to correct this.
