Provided you load it in the right order, yes. The led class will need
to be loaded *before* fujitsu-laptop.

It is odd that you get duplicate LED devices. It does appear to be a
phantom device.

Especially as that one works.

So you get no log entries for the "wrong" platform device, but you do
get entries for the second, working device? (It wouldn't make sense to
me if the LED state changes without log entries being made, as it takes
a FUNC callback to do it)

The DSDT looks good, the keyboard LED is presented as the driver
expects. Seems very similar to the U810.
