Ok, first bisect attempt reports:

f4c80d5a16eb4b08a0d9ade154af1ebdc63f5752 is the first bad commit
HEAD ist jetzt bei f4c80d5a16eb Merge tag 'sound-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Well, this is a "merge". And a merge may hide the real reason
due to history that may have separate before the first good

So what I have to do is to restart/redo the bisect starting

Let's try again with letux-4.6-rc1..letux-4.7-rc1
