I'm almost positive that these are alsa-driver configure errors or omissions. I can't (yet) find a kernel config that will avoid them. The fixes below are harmless, and they will allow you to get the driver compiled.

Whoops!  I tried reapplied the changes to a fresh checkout, and now it
builds just fine. I applied the change to:
   configure.in 
   alsa-kernel/pci/hda/patch_via.c
I have to wait until tonight to test.
Thank you!
