I dropped the ball here and didn't get any fix for this in v6.15.

Why do we need pci_pwrctrl_create_device() in drivers/pci/probe.c?
The obvious thing would have been to put the implementation in
drivers/pci/pwrctrl with a stub in drivers/pci/pci.h, so I assume
there's some reason we can't do that?
