Subject[PATCH 5/6] hwmon: (npcm750-pwm-fan) Use devm_thermal_of_cooling_device_register
Date
Use devm_thermal_of_cooling_device_register() to register the cooling
device. As a side effect, this fixes a driver bug:
thermal_cooling_device_unregister() was not called on device removal.

Fixes: f1fd4a4db777 ("hwmon: Add NPCM7xx PWM and Fan driver")
