This is no longer needed with these:

And this is why you need "brightness_in_hardware=true" to tell the userspace
software to not react on these keyevents because the brightness get set
directly by the keys in the hardware. Currently it isn't a problem since you
don't get these events.
The question is: do we really need the events get send to HAL if the change is
done in hardware?
