Hi Stephen,

We have provided fix for build error and pushed patch for upstream review.

Patch title: " ASoC: amd: fix ACPI dependency compile errors and warnings"
patch link:
https://lore.kernel.org/lkml/20220706205515.2485601-1-Vijendar.Mukunda@amd.com/

We will resend the fix for upstream review.

Thanks,
Vijendar
