Hmm, Linus, that was a week ago and I still can't spot the fix in -next
or
https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl.git
; am I missing something or did something come up?

Furthermore Christian seems to grow impatient -- and I do as well, as I
recently couldn't wake up my laptop due to this while on the road. :-/
As at least one of the affected machines is quite popular in Linux
community, I'd prefer if we can fix this rather sooner than later.
Linus, if you are busy, I could ask the other Linus to pick this up
straight from the list if that's okay for you.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
