PNP: mark resources that conflict with PCI devices "disabled"
Both the PNP/PCI conflict detection quirk and the PNP system driver must use the same mechanism to mark resources as disabled. I think it's best to keep the resource and to keep the type bit (IORESOURCE_MEM, etc), so that we match the list from firmware as closely as possible.
