I don't think it can be reverted.

Can you just try to revert the changes in pci_raw_set_power_state() and check if that has any effect (it shouldn't)?

So this is after kexec?
What happens if you remove just the
/* Check if we're already there */ if (dev->current_state == state) return 0;
part from pci_set_power_state()?
