PCI: Delay final fixups until resources are assigned
Commit 4f535093cf "PCI: Put pci_dev in device tree as early as possible" moved final fixups from pci_bus_add_device() to pci_device_add(). But pci_device_add() happens before resource assignment, so BARs may not be valid yet. Typical flow for hot-add: pciehp_configure_device pci_scan_slot pci_scan_single_device pci_device_add pci_fixup_device(pci_fixup_final, dev) # previous location # resource assignment happens here pci_bus_add_devices pci_bus_add_device pci_fixup_device(pci_fixup_final, dev) # new location [bhelgaas: changelog, move fixups to pci_bus_add_device()] Reference: https://lkml.kernel.org/r/20130415182614.GB9224@xanatos Reported-by: David Bulkow <David.Bulkow@stratus.com> Tested-by: David Bulkow <David.Bulkow@stratus.com> Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> CC: stable@vger.kernel.org # v3.9+
