dmesg (using the "debug" boot paramater)

Referring to bug posted to the "libinput" bug tracker:
https://gitlab.freedesktop.org/libinput/libinput/issues/253

There is no driver support for the input devices of the ASUS ROG Zephyrus M (GM501GM), which provides important keyboard functionality for a laptop. Visa vi screen brightness, airplane mode, display power switch, etc. I was told that there is apparently no support for this keyboard on a kernel level as the keycodes are registered as ABS_MISC events. It should be noted that neither asus_wmi or asus-nb-wmi provides this functionality, nor with the absence of either. In addition to the link above I will provide a lshw file and dmesg log.
