But during hysteresis attribute creation, if this operation is defined then only it enables hysteresis write access. It leads to a case where hysteresis sysfs will be read only for a thermal zone when its set_trip_hyst() operation is not defined. Fix this by removing the check whether set_trip_hyst() operation is defined or not during hysteresis attribute initialization.
