commit eb09074bdb05ffd6bfe77f8b4a41b76ef78c997b upstream.
The touchpad of this device is both connected via PS/2 and i2c. This causes strange behavior when both driver fight for control. The easy fix is to prevent the PS/2 driver from accessing the mouse port as the full feature set of the touchpad is only supported in the i2c interface anyway.
The strange behavior in this case is, that when an external screen is connected and the notebook is closed, the pointer on the external screen is moving to the lower right corner. When the notebook is opened again, this movement stops, but the touchpad clicks are unresponsive afterwards until reboot.
