Subject: [PATCH] ASoC: mediatek: mt8183: support machine driver with max98357b
Git-commit: 08145535a8321eb330fceb9e6542b51091f7d3c6
Patch-mainline: v5.9-rc1
References: jsc#SLE-16518

Supports machine driver with max98357b
("mt8183-mt6358-ts3a227-max98357b").

The key difference from max98357a: max98357b needs to use left
justified format.
