[PATCH] acpi bridge hotadd: Link newly created pci child bus to its parent on creation
When a pci child bus is created, add it to the parent's children list
immediately rather than waiting till pci_bus_add_devices(). For hot-plug
bridges/devices, pci_bus_add_devices() may be called much later, after they
have been properly configured. In the meantime, this allows us to use the
normal pci bus search functions for the hot-plug bridges/buses.
