[alsa-devel] [PATCH 1/3] ASoC: core: support driver alias names for FE topology overrides

[Pierre-Louis Bossart]

When the same machine driver is reused between platforms but with a
different alias, using the driver name is not enough. Add additional
fallback case to use the card device name.

Tested on GeminiLake with bxt_da7219_max98357a machine driver
