linux-next: build failure after merge of the sound-asoc tree

Hi all,

After merging the sound-asoc tree, today's linux-next build (x86_64
allmodconfig) failed like this:

ERROR: modpost: "snd_soc_acpi_amd_acp_machines" [sound/soc/amd/acp/snd-acp-renoir.ko] undefined!

Caused by commit

  e646b51f5dd5 ("ASoC: amd: acp: Add callback for machine driver on ACP")

I have used the sound-asoc tree from next-20211022 for today.
