Which ensures that the +PCI driver core will initialize the of_node field +before starting the scan. + +Also remove the local assignment of bus->dev.of_node, +it is not needed after the patch. + +Signed-off-by: Gabor Juhos <juhosg@openwrt.org> +Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> +--- + arch/mips/pci/pci.c | 8 +++++++- + 1 file changed, 7 insertions(+), 1 deletion(-) + +--- a/arch/mips/pci/pci.c ++++ b/arch/mips/pci/pci.c +@@ -115,7 +115,6 @@ static void pcibios_scanbus(struct pci_c + pci_bus_assign_resources(bus); + pci_enable_bridges(bus); + } +- bus->dev.of_node = hose->of_node; + } + } + +@@ -169,6 +168,13 @@ void pci_load_of_ranges(struct pci_contr + } + } + } ++ ++struct device_node *pcibios_get_phb_of_node(struct pci_bus *bus) ++{ ++ struct pci_controller *hose = bus->sysdata; ++ ++ return of_node_get(hose->of_node); ++} + #endif + + static DEFINE_MUTEX(pci_scan_mutex); |
