Subject: [PATCH AUTOSEL 5.4 05/23] ASoC: cs35l36: Update digital volume TLV

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

[ Upstream commit 5005a2345825eb8346546d99bfe669f73111b5c5 ]

The digital volume TLV specifies the step as 0.25dB but the actual step
of the control is 0.125dB. Update the TLV to correct this.
