pci_revert_fw_address() is used to reinstate a PCI device's original FW-assigned BIOS BAR value(s) if normal resource assignment fails. When attempting to reinstate an address, the point within the resource tree from which to attempt the new resource request should be the parent resource corresponding to the device, not the base of the resource tree (ioport_resource or iomem_resource). For PCI devices this would typically be the resource corresponding to the upstream PCI host bridge or P2P bridge aperture. This patch sets the point within the resource tree to attempt a new resource assignment request to the PCI device's parent resource and only if that fails does it fall back to the base ioport_resource or iomem_resource.
