Wysocki It is invalid to call for_each_thermal_trip() on an unregistered thermal zone anyway, and as per thermal_zone_device_register_with_trips(), the trips[] table must be present if num_trips is greater than zero for the given thermal zone. Hence, the trips check in for_each_thermal_trip() is redundant and so it can be dropped. Signed-off-by: Rafael J.
