the patch seems invalid for me.
all of them are in the ifdef's which 2.6.x shouldn't pass.
i guess alsa-driver's configure script didn't check it correctly, or
you copied the wrong files into your kernel tree.

just run configure on the top of alsa-driver (with options if
necessary), or copy the files of alsa-kernel tree (not alsa-driver) to
linux source tree and make modules there.
