The driver is controlling the ATKD device, which has a HID of ATK0101.
These devices are all underneath it...

And this one isn't, which is a bit jarring. Looking closer, it's under
the LEN0014 device, which means that you're trying to touch a method
that belongs to a device other than the one this driver is bound to.
That's wrong. You want a separate ACPI driver for the LEN0014 device,
and this should be called for there. Looking at it, you seem to get
rfkill as well (the GWAN/SWAN, GBDC/SBDF and GUWB/SUWB methods) and
maybe some other stuff.

So this shouldn't go in asus-laptop. You'll need to add another separate
driver for the SL-specific functionality.
