From: Alexander Mikhaylenko <exalm7...@gmail.com> commit 9843f3e08e2144724be7148e08d77a195dea257a upstream.
They are capable of using intertouch and it works well with psmouse.synaptics_intertouch=1, so add them to the list. Without it, scrolling and gestures are jumpy, three-finger pinch gesture doesn't work and three- or four-finger swipes sometimes get stuck.
