[Bug 1798363]

This bug is present on an Asus FX504G. It does not matter if one is
running Synaptics or libinput. The error message will eventually cause
the touchpad to stop operating completely. It will start working again
after a period of time. However, to have it operate again immediately, I
have to type: rmmod hid-multitouch && modprobe hid-multitouch in a root
terminal.

This is on Manjaro 18.03 running Gnome 3.30.2 with kernel:
