Subject: [PATCH] ASoC: amd: Return -ENODEV for non-existing ACPI call
Git-commit: ab5893fdc0693e4f747ef26194b6bbf628bdb044
Patch-mainline: v5.11-rc1
References: git-fixes

AMD Renoir driver tries to identify the presence of DMIC by evaluating
ACPI _WOV entry, and it returns -EINVAL when the ACPI call failed.
This ended up an error message like
  snd_rn_pci_acp3x: probe of 0000:04:00.5 failed with error -22
although the system is correctly set up.

For avoiding such a superfluous error message, change the return value
to -ENODEV.  Then the driver core just skips to the next one without
complaining.
