[PATCH 1/4] ASoC: SOF: amd: Make ACP core code generic for newer SOC transition

Tue Sep 13 16:53:29 CEST 2022


Hello,

Care to add the Reviewed-by tags received on SOF github?

https://github.com/thesofproject/linux/pull/3749

 From time to time someone at intel runs a script and does a rebase
which picks the reviewed-by tags into topic/sof-dev-rebase branch.

thanks,
Daniel.
