Because the __thermal_cdev_update function traverses the cooling_device->thermal_instances list to obtain the maximum target state, and then the cooling device sets the maximum cooling state. However, the power_actor_set_power function only updates the target value of thermal_zone->thermal_instances to the target state, and does not update the target value of cooling_device->thermal_instances, resulting in the target being 0 all the time.
