The 5th generation Thinkpad X1 Carbons use Synaptics touchpads accessible over SMBus/RMI, combined with ALPS or Elantech trackpoint devices instead of classic IBM/Lenovo trackpoints. Unfortunately there is no way for ALPS driver to detect whether it is dealing with touchpad + trackpoint combination or just a trackpoint, so we end up with a "phantom" dualpoint ALPS device in addition to real touchpad and trackpoint. Given that we do not have any special advanced handling for ALPS or Elantech trackpoints (unlike IBM trackpoints that have separate driver and a host of options) we are better off keeping the trackpoints in PS/2 emulation mode. We achieve that by setting serio type to SERIO_PS_PSTHRU, which will limit number of protocols psmouse driver will try. In addition to getting rid of the "phantom" touchpads, this will also speed up probing of F03 pass-through port.
