From: Ben Sagal <[email protected]>
commit bce4f9e764c36bc35dd5c9cf9e057c09f422397d upstream.
The LEN2006 Synaptics touchpad (as found in Thinkpad E540) returns wrong
min max values.

> 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]
