Subject: [PATCH] ASoC: cs35l41: Add ASP TX3/4 source to register patch
Git-commit: 46b0d050c8c7df6dfb2c376aaa149bf2cfc5ca3e
Patch-mainline: v5.19-rc6
References: bsc#1203699
The mixer controls for ASP TX3/4 are set to values that are not included
in their enumeration control. This will cause spurious event
notifications when the controls are first changed, as the register value
changes whilst the actual visible enumeration value does not. Use the
register patch to set them to a known value, zero, which equates to zero
fill, thereby avoiding the spurious notifications.
