  "message": "PCI: Assign resources before drivers claim devices (pci_scan_root_bus())\n\nPreviously, pci_scan_root_bus() created a root PCI bus, enumerated the\ndevices on it, and called pci_bus_add_devices(), which made the devices\navailable for drivers to claim them.\n\nMost callers assigned resources to devices after pci_scan_root_bus()\nreturns, which may be after drivers have claimed the devices.  This is\nincorrect; the PCI core should not change device resources while a driver\nis managing the device.\n\nRemove pci_bus_add_devices() from pci_scan_root_bus() and do it after any\nresource assignment in the callers.\n\nNote that ARM\u0027s pci_common_init_dev() already called pci_bus_add_devices()\nafter pci_scan_root_bus(), so we only need to remove the first call:\n\n  pci_common_init_dev\n    pcibios_init_hw\n      pci_scan_root_bus\n        pci_bus_add_devices        # first call\n    pci_bus_assign_resources\n    pci_bus_add_devices            # second call\n\n[bhelgaas: changelog, drop \"root_bus\" var in alpha common_init_pci(),\nreturn failure earlier in mn10300, add \"return\" in x86 pcibios_scan_root(),\nreturn early if xtensa platform_pcibios_fixup() fails]\nSigned-off-by: Yijing Wang \u003cwangyijing@huawei.com\u003e\nSigned-off-by: Bjorn Helgaas \u003cbhelgaas@google.com\u003e\nCC: Richard Henderson \u003crth@twiddle.net\u003e\nCC: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCC: Matt Turner \u003cmattst88@gmail.com\u003e\nCC: David Howells \u003cdhowells@redhat.com\u003e\nCC: Tony Luck \u003ctony.luck@intel.com\u003e\nCC: Michal Simek \u003cmonstr@monstr.eu\u003e\nCC: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCC: Koichi Yasutake \u003cyasutake.koichi@jp.panasonic.com\u003e\nCC: Sebastian Ott \u003csebott@linux.vnet.ibm.com\u003e\nCC: \"David S.
