#     powerpc/pci: Hotplug driver bridge support
#     
#     There is an issue with the hotplug operation when it's done on the
#     bridge/switch slot. The bridge-port and devices behind the bridge, which
#     become offline by hot-unplug operation, don't get hot-plugged/enabled
#     by doing hot-plug operation on that slot. Only the first port of the
#     bridge gets enabled and the remaining port/devices remain unplugged. The
#     hot plug/unplug operation is done by the hotplug driver (drivers/pci/
#     hotplug/pnv_php.c).
#     
#     This behavior is due to missing code for the switch/bridge. The existing
#     driver depends on pci_hp_add_devices() function for device enablement.
#     This function calls pci_scan_slot() on only one device-node/port of the
#     bridge, not on all the siblings' device-node/port.
#     
#     The missing code needs to be added which will find all the sibling
#     device-nodes/bridge-ports and will run explicit pci_scan_slot()
#     on those. A new function has been added for this purpose
#     which is invoked from pci_hp_add_devices(). This new function
#     pci_traverse_sibling_nodes_and_scan_slot() gets all the sibling
#     bridge-ports by traversal and explicitly invokes pci_scan_slot() on
#     them.
