Thanks for your confirmation. 

My gut feeling is that this isn't very urgent and taking this as merge
window material for 6.18-rc1 is fine. I still applied it to
https://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux.git pwm/fixes
and will send it along if something more urgent pops up. Please tell me
if you think I should bother Linus with it and get it into 6.17.

Best regards
Uwe
