+1.1.5 struct thermal_zone_device *devm_thermal_zone_of_sensor_register(
+ struct device *dev, int sensor_id,
+ void *data, const struct thermal_zone_of_device_ops *ops)
+
+ This interface is resource managed version of
+ thermal_zone_of_sensor_register().
+ All details of thermal_zone_of_sensor_register() described in
+ section 1.1.3 is applicable here.
+ The benefit of using this interface to register sensor is that it
+ is not require to explicitly call thermal_zone_of_sensor_unregister()
+ in error path or during driver unbinding as this is done by driver
+ resource manager.

+1.1.6 void devm_thermal_zone_of_sensor_unregister(struct device *dev,

+
+ This interface is resource managed version of
+ thermal_zone_of_sensor_unregister().
+ All details of thermal_zone_of_sensor_unregister() described in
+ section 1.1.4 is applicable here.
+ Normally this function will not need to be called and the resource
+ management code will ensure that the resource is freed.
