Hi Takashi, I don't think you have the result in the sound tree (git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git branch for-next). Yesterday it was a fairly linear tree with head commit 7421a1671abe ("ALSA: pcm: include pcm_local.h and remove some extraneous tabs") based on commit f83914fdfcc3 ("ALSA: usb-audio: fix Amanero Combo384 quirk on big-endian hosts"). Now it is a tree with 687 commits (realative to Linus' tree) with 651 merge commits in it. :-(
