Hi Takashi,

After merging the sound tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

sound/ppc/tumbler.c: In function 'tumbler_find_device':
sound/ppc/tumbler.c:1143: error: implicit declaration of function 'machine_is_compatible'

Caused by commit 819ef70b135ba66cd1659c913255686bf931e3d4 ("ALSA:
powermac - Reverse HP detection on G4 DA").  machine_is_compatible was
renamed to of_machine_is_compatible by commit
71a157e8edca55198e808f8561dd49017a54ee34 ("of: add 'of_' prefix to
machine_is_compatible()") in Linus' tree since Feb 26, 2010 (and is in
v2.6.34-rc1).

I have used the version of the sound tree from next-20100401 for today.
