The call to thermal_cdev_update() causes any fan connected to the chip to stop immediately. If the thermal subsystem is not set up to actually handle the chip as cooling device, the remains stopped until is is restarted manually with a write to a sysfs attribute. There is evidence that thermal_cdev_update() should only be called from thermal governors, not from thermal cooling device drivers. Drop the call.
