It results all around the thermal framework code a check against the ops pointer and different action adding more complexity and making the code less readable and understandable. A zero hysteresis value is perfectly valid, so instead of adding more circumvolutions in the code, create unconditionnaly the hysteresis and use the thermal_zone_get_trip() function which returns a zero hysteresis if the get_trip_hyst() is not defined.
