From: Ulrich Dangel <uli-kernel@xxxxxxxxx>
When pressing any button belonging to the touchpoint, the generated click
events dont belong to the touchpoint but to the touchpad.
This patch fixes this behaviour, the events will be sent via the correct
device, so scrolling with touchpoint is possible.
The patch compiles cleanly and has been tested successfully on my machine.
