Subject: [PATCH] ASoC: snd-sof-intel-hda-common - add hda_model parameter and pass it to HDA codec driver
Git-commit: b8d3ad51dfec3631763cfef3d30c16f40140058b
Patch-mainline: v5.8-rc1
References: jsc#SLE-16518
It may be useful to pass the specific model to the generic HDA codec
routines like the legacy HDA driver (snd-hda-intel) allows.
The model name "sofbus" is tricky anyway.
