From: Arnd Bergmann <arnd@xxxxxxxx> The acp-platform driver now needs the ACPI helpers: ld.lld: error: undefined symbol: snd_soc_acpi_find_machine >>> referenced by acp-platform.c >>> soc/amd/acp/acp-platform.o:(acp_machine_select) in archive sound/built-in.a ld.lld: error: undefined symbol: snd_soc_acpi_codec_list >>> referenced by acp-renoir.c >>> soc/amd/acp/acp-renoir.o:(snd_soc_acpi_amd_acp_machines) in archive sound/built-in.a Other drivers using this interface, select SND_SOC_ACPI, so do the same thing here.
