Hi Chris,
there is no real point of having a separate driver from hid-asus. The
HID tree prefer to group drivers by vendors, so these keyboards should
be supported through hid-asus.
Please fold the patch in hid-asus and probably add a special quirk for
these keyboards in input_mapping. With a little luck, the quirk won't
even be required and we can apply these mapping to all Asus keyboards.

Not sure this belongs here. You are checking this in a local driver, not
in the generic hid-input path, so there is no point in telling everybody
that ASUS ROG keyboards are using this usage page.
