I have an ASUS UX303 running Fedora 23, and I get this:

This code will not build for kernel 4.3. It has been merged since kernel 4.2.
If your touchpad does not work, it must be not a Focaltech.

As told here I have also an Asus UX303 with a non working Focaltech touchpad. It respond with evtest but not work either way, or work with proto=imps but without multitouch. Not sure if related to this launchpad bug.
