Subject: [PATCH AUTOSEL 5.18 09/47] ASoC: cs42l52: Fix TLV scales for mixer controls

From: Charles Keepax <ckeepax@...nsource.cirrus.com>

[ Upstream commit 8bf5aabf524eec61013e506f764a0b2652dc5665 ]

The datasheet specifies the range of the mixer volumes as between
-51.5dB and 12dB with a 0.5dB step. Update the TLVs for this.
