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.

 
Thank you very much, Bjorn! The patchset looks good to me.

Thanks,
-- Dexuan
