Dexuan, the important thing here is the first patch, which is your [1],
which I modified by doing pci_restore_state() as well as setting to D0:

pci_set_power_state(pci_dev, PCI_D0);
pci_restore_state(pci_dev);

I'm proposing some more patches on top. None are relevant to the problem
you're solving; they're just minor doc and other updates in the same area.

Rafael, if you have a chance to look at these, I'd appreciate it. I tried
to make the doc match the code, but I'm no PM expert.
