Assuming the preparation series gets accepted, maybe we can give it a
try via my pmdomain tree? Or do expect to land a lot of code that
could conflict?

I also realized that I already have a different series [1] queued in
my pmdomain tree from Dikshita Agarwal (reviewed by Bryan), that moves
an existing call for dev_pm_domain_attach() to the new
devm_pm_domain_attach() helper. So far I haven't received any reports
about conflicts from linux-next, so it looks good I think.

Kind regards
Uffe
