Thanks for all the hints Alan.
I think I figured it out, the below patch seems to fix it for me. Looking
at other drivers resume functions it seems we're missing the
pm_runtime_disable()->set_active()->enable() dance. Doing that fixes the
warning and the dev_err() in driver/base/power.
I don't see xhci-plat.c doing that, I wonder if it needs it too.
I'm not well versed about the details and the rules here. So my fix could be
a hack, though it does seem the right thing to do.
I wonder why the power core doesn't handle this transparently..
Requested dmesg is attached too.
