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.

My guess is that the error of configure script is the only point we
need to fix.

Don't do this.  This part shouldn't be compiled at all for recent
kernels.  This is, again, the problem of configure script that
detected the codes wrongly.

So, could you guys show config.log?  Otherwise it's hard to know
what's really wrong.
