When registering the hwmon device, we pass NULL as the device. While this doesn't result in any immediate breakage, it leaves the hwmon device at the root of the virtual devices, rather than attached to the thermal zone hierarchy.
Instead, let's pass the actual device, which is part of the thermal_zone_device structure. This also avoids the rather unpleasant ""NULL device *" which can be generated by dev_{err,info} in the hwmon subsystem.
