From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>
Convert agpgart-efficeon from legacy PCI power management to the generic
power management framework.
Previously agpgart-efficeon used legacy PCI power management, which means
agp_efficeon_suspend() and agp_efficeon_resume() were responsible for both
device-specific things and generic PCI things like saving and restoring
config space and managing power state.
In this case, agp_efficeon_suspend() was empty, and agp_efficeon_resume()
already did only device-specific things, so simply convert it to take a
struct device * instead of a struct pci_dev *.
Based on 0aeddbd0cb07 ("via-agp: convert to generic power management") by
Vaibhav Gupta <vaibhavgupta40@xxxxxxxxx>.
