Subject: [PATCH] ASoC: mediatek: mt8183-da7219: support machine driver with rt1015
Git-commit: 9e30251fb22eccaf2199cdfdc02c90459f83bea7
Patch-mainline: v5.9-rc1
References: jsc#SLE-16518
Supports machine driver with rt1015 ("mt8183-da7219-rt1015"). Embeds in
existing mt8183-da7219-max98357.c because they share most of the code.
