That's not the problem, since function and definition are in the same
module.
You didn't send your .config, but looking at the code it seems
CONFIG_PM=n was the culprit.
As a workaround, it should work after enabling the following option:
Power management options (ACPI, APM)
Power Management support
This is only a workaround, I've Cc'ed the ALSA maintainers for a real
fix.
