From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>
Convert agpgart-intel from legacy PCI power management to the generic power
management framework.
Previously agpgart-intel used legacy PCI power management, and
agp_intel_resume() was responsible for both device-specific things and
generic PCI things like saving and restoring config space and managing
power state.
In this case, agp_intel_suspend() was empty, and agp_intel_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>.
