Subject: [PATCH] ASoC: mediatek: mt8183: support machine driver with rt1015
Git-commit: f4fb4fef49664e64f4f40e9e8db11f785fbc79a4
Patch-mainline: v5.9-rc1
References: jsc#SLE-16518
Supports machine driver with rt1015 ("mt8183-mt6358-ts3a227-rt1015").
Embeds in existing mt8183-mt6358-ts3a227-max98357.c because they share
most of the code.
