[PATCH v2] Fix strange behavior of touchpad on Clevo NS70PU

[PATCH v2] Fix strange behavior of touchpad on Clevo NS70PU

[Werner Sembach]

When closing the laptop lid with an external screen connected, the mouse
pointer has a constant movement to the lower right corner. Opening the
lid again stops this movement, but after that the touchpad does no longer
register clicks.

The touchpad is connected both via i2c-hid and PS/2, the predecessor of
this device (NS70MU) has the same layout in this regard and also strange
behaviour caused by the psmouse and the i2c-hid driver fighting over
touchpad control. This fix is reusing the same workaround by just
disabling the PS/2 aux port, that is only used by the touchpad, to give the
i2c-hid driver the lone control over the touchpad.

v2: Rebased on current master
