commit 98e6e286d7b01deb7453b717aa38ebb69d6cefc0
Author: Rafael J. Wysocki <rjw@...k.pl>
Date: Wed Jan 7 13:10:35 2009 +0100
PCI PM: Register power state of devices during initialization
Use the observation that the power state of a PCI device can be
loaded into its pci_dev structure as soon as pci_pm_init() is run for
it and make that happen.
