Ack, the problem still exists and is fixed by this patch

Tested-by: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>


On a related note, with this randconfig we have a separate problem on an
AMD patch on the SOF tree

ERROR: modpost: "snd_amd_acp_find_config"
[sound/soc/amd/snd-acp-config] is a static EXPORT_SYMBOL

That wasn't detected earlier, any idea what Kconfig option I need to
enable to filter this out?
