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
