This patchset is not proper yet.

Your first patch includes code difference under line 26, thus it expects
existence of a file 'sound/drivers/xen-front.c' in tree. However, the
file is not introduced in any upstream yet; at least, Linus's tree and
Iwai-san's tree.

You still work on your local branch, not for us.
