[PATCH] Extra buttons on Acer Ferrari 4000 laptop touchpad are not recognized

[Alan Coopersmith]

From: Casper Dik <casper.dik at oracle.com>

The code was checking for a value of exactly 1, while the Synaptics
docs at http://www.synaptics.com/sites/default/files/511-000275-01rA.pdf
say:

    Extended Model ID. This query returns the product ID, additional
    capability bits, and additional bits to widen the infoSensor
    field. infoSensor is a part of the Model ID query (query $03).
    The Extended Model ID query is only present if nExtendedQueries
    is *greater than* or equal to 1.
