interface. It will also silent the zone by remove the .get_temp() and
get_trend() thermal zone device callbacks.
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,
struct thermal_zone_device *tzd)
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.
