Subject: [PATCH 3.12 180/182] Input: synaptics - add min/max quirk for ThinkPad T431s, L440, L540, S1 Yoga and X1

From: Hans de Goede <hdegoede@...hat.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 46a2986ebbe18757c2d8c352f8fb6e0f4f0754e3 upstream.

We expect that all the Haswell series will need such quirks, sigh.

The T431s seems to be T430 hardware in a T440s case, using the T440s touchpad,
with the same min/max issue.

The X1 Carbon 3rd generation name says 2nd while it is a 3rd generation.

The X1 and T431s share a PnPID with the T540p, but the reported ranges are
closer to those of the T440s.

HdG: Squashed 5 quirk patches into one. T431s + L440 + L540 are written by me,
S1 Yoga and X1 are written by Benjamin Tissoires.

Hdg: Standardized S1 Yoga and X1 values, Yoga uses the same touchpad as the
X240, X1 uses the same touchpad as the T440.
