Oh, it seems that your patch was lost in the patch queue before ALSA
1.0.15 release.  Sorry, I applied the last one now to ALSA HG tree
together with this one.

The patch to arch/ppc/syslib/virtex_device.c isn't still applied
(because it's outside the ALSA HG tree).  For applying this to alsa
git tree, Jaroslav would need to apply manually.

Jaroslav, could you add it please?

... Or, feel free to apply that patch to ppc tree separately.  It
shouldn't break anything, at least :)
