OK, thanks. Then I'll queue this clean-up patch to ALSA tree.

There are three patches.
- Ingo's patch to reduce latency. This was applied after rc6, and
reverted after rc7.
- My first test patch
- My second test patch (clean-up patch you tested lastly)

but doesn't point mm branch.

And, Linus and ALSA git trees are likely out of sync.
