    Subject[PATCH 3.10 46/48] Input: synaptics - add min/max quirk for ThinkPad T431s, L440, L540, S1 Yoga and X1
    Date
    3.10-stable review patch.  If anyone has any objections, please let me know.

    ------------------

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

    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.
