a72f7ea693101cc48bafbb4db6bb437d828011c4ql Uses a bus specific algorithm to retrieve a driver image handle for a controller.
a72f7ea693101cc48bafbb4db6bb437d828011c4ql @param This A pointer to the EFI_BUS_SPECIFIC_DRIVER_OVERRIDE_PROTOCOL instance.
a72f7ea693101cc48bafbb4db6bb437d828011c4ql @param DriverImageHandle On input, a pointer to the previous driver image handle returned
