The pcie_port_bus_type must be registered before drivers that depend on it can be registered. Those drivers include: pcied_init() # PCIe native hotplug driver aer_service_init() # AER driver dpc_service_init() # DPC driver pcie_pme_service_init() # PME driver Previously we registered pcie_port_bus_type from pcie_portdrv_init(), a device_initcall. The callers of pcie_port_service_register() (above) are also device_initcalls. This is fragile because the device_initcall ordering depends on link order, which is not explicit. Register pcie_port_bus_type from pci_driver_init() along with pci_bus_type. This removes the link order dependency between portdrv and the pciehp, AER, DPC, and PCIe PME drivers.
