Subject: [PATCH AUTOSEL 5.10 09/10] ASoC: cs42l51: Correct PGA Volume minimum value

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

[ Upstream commit 3d1bb6cc1a654c8693a85b1d262e610196edec8b ]

The table in the datasheet actually shows the volume values in the wrong
order, with the two -3dB values being reversed. This appears to have
caused the lower of the two values to be used in the driver when the
higher should have been, correct this mixup.
