That is because your for-linus was still 4.20-rc based when
I created it.
It's never been 4.20-rc based. After the initial merge, it got based
on a random commit in the merge window:
commit 3acbd2de6bc3af215c6ed7732dfc097d1e238503

Merge tag 'sound-4.20-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
and has been ever since.
That was because I rebased it when your for-linus didn't include Ming's
buggy version of the brd commit. Sorry for the mixup..
