# DF-4651 fix validation (guest): build snd_fm801.ko from the patched
# source.  The guest's /usr/src copy is backed up, patched with fix.diff
# (reordered attach: IRQ + dma tag + pcm_register BEFORE AC97_CREATE/
# mixer_init; mixer_init failure destroys the codec inline; oops: tears
# the handler down before unmapping MMIO), the module is compiled with
# the standard kernel-module make, and the pristine source is restored.
