Wysocki Add a wrapper around for_each_thermal_trip(), called thermal_zone_for_each_trip(), that will invoke the former under the thermal zone lock and pass its return value to the caller. Two drivers will be modified subsequently to use this new function. No functional impact. Signed-off-by: Rafael J.
