This seems to be related to commit 4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff.

It clears dev->state_saved blindly, but pci_pm_resume() calls
pci_restore_standard_config() before pm->resume() (by probably
historical reason).

So, I guess it became the cause of restore regression before changing
PCI power state. It might be better to revert
4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff for now, until changing pci
generic stuff.

Thanks.
