No, Takashi-san is telling you to try commenting this out and recompile
and see if the problem goes away.  If so then we can figure out how to
detect this MPU-less device and fix it in ALSA CVS.  He probably does
not have access to the hardware to test it himself.

This is a pretty common issue with ALSA because a lot of cards that
purport to be the same as another have small differences, and the alsa
devs can't possibly test every single device.
