I don't see that symbol on linux-next at all, so this must be a bug
that is specific to the
current SOF tree. The message tells you that snd_amd_acp_find_config should
not be exported at all since it's static, or it should not be marked
static because it
is used by other modules. IOW having a symbol that is both static and exported
means it's not usable from built-in drivers.
