Yes, because a) I was unsure what he didn't like about the subject, and
(more importantly) b) I split the patch in question. I should have
written that in the cover letter, sorry.

(Note I only announced to have fixed the subject prefix of the pwm
patch. I assume you won't include that in your pull request, but if you
do, please do s/-/: / on it. That's another thing I failed with for this
series.)

Best regards
