35 Uses a bus specific algorithm to retrieve a driver image handle for a controller.
37 @param This A pointer to the EFI_BUS_SPECIFIC_DRIVER_
38 OVERRIDE_PROTOCOL instance.
39 @param DriverImageHandle On input, a pointer to the previous driver image handle returned
40 by GetDriver(). On output, a pointer to the next driver
41 image handle. Passing in a NULL, will return the first driver
44 @retval EFI_SUCCESS A bus specific override driver is returned in DriverImageHandle.
45 @retval EFI_NOT_FOUND The end of the list of override drivers was reached.
46 @retval EFI_INVALID_PARAMETER DriverImageHandle is not a handle that was returned on a
47 previous call to GetDriver().
