RE bug: https://bugzilla.kernel.org/show_bug.cgi?id=88211

The LEN2006 Synaptics touchpad (as found in my thinkpad E540) returns
wrong min max values.

touchpad-edge-detector output:

 Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event6
 Move one finger around the touchpad to detect the actual edges
 Kernel says:    x [1472..5674], y [1408..4684]
 Touchpad sends: x [1264..5675], y [1171..4688]

the patch is against 3.17.2
