But I suspect that the iwlwifi firmware is loaded during interface up
(and unloaded during interface down) and in that case
register/unregister would be happening all the time. That doesn't sound
like a good idea. I would rather try to fix the thermal interface to
handle the cases when the measurement is not available.
