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. -- Cheers, Stephen Rothwell
