agp: efficeon-agp: do not use PCI resources before pci_enable_device()
IRQ and resource[] may not have correct values until after PCI hotplug setup occurs at pci_enable_device() time. The semantic match that finds this problem is as follows: // <smpl> @@ identifier x; identifier request ~= "pci_request.*|pci_resource.*"; @@ ( * x->irq | * x->resource | * request(x, ...) ) ... *pci_enable_device(x) // </smpl> Signed-off-by: Kulikov Vasiliy <segooon@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
