Subject: [PATCH libinput 4/4] touchpad: disable trackpoint palm detection on
small touchpads
Tested on three laptops here, Lenovo T61, X220 and an HP EliteBook (?), all
with small touchpads. It's hard to have a hand position where the palm touches
the touchpad while using the trackpoint. So we might as well save us the
effort of monitoring events and enabling/disabling it on demand.
As a side-effect this fixes 1233844, but that's more a coincidence.
