Where did you get the snapshot tarball from?  It must be:
   ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz

Note that this is different from the tarball in alsa-project.org.  The
one in alsa-project.org is far behind the latest version.  It explains
why the patch failed.

(BTW, try the above tarball first without patching.)

In general, it's recommended to build all drivers, and use the update
directory.  The partial builds cause often dependency problems.
As mentioned in INSTALL, a safe combination is:

	% ./configure --with-debug=full --enable-dynamic-minors \
		--with-moddir=updates

This will install the resultant modules into
/lib/modules/$VERSION/updates/*.  So, you can remove these files
easily and back to the original state.
