Unfortunately I didn't read your cover email carefully before queuing this up.
I now see that it has dependencies that aren't present in v3.11-rc and
thus I have temporarily dropped it.

It seems to me that the dependencies could be provided by
the topic/car branch of
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git.

Morimoto-san, is this correct?
If so, Mark, would it be possible for you to provide topic/car
or similar as stable branch for me to use as a base?
My intention is to queue these up for v3.13.
