Previously dev2 device was used for both external PS/2 mouse and internal trackstick device (if available). This change introduces dev3 device which is used for external PS/2 mouse data and dev2 is now used only for trackstick. In case that trackstick is not present dev2 is not created, so userspace does not see non existent device in system. Because laptops with ALPS devices often do not use i8042 active multiplexing all data (from touchpad, trackstick and external PS/2 mouse) come to one port. So it is not possible to know if external PS/2 mouse is connected or not. In most cases external PS/2 mouse is not connected so driver will create dev3 input device after first bare PS/2 packet will be received. So there will not be "ghost" input device. This change also helps in identifying possible problems in future if driver decides to report 6-bytes trackstick packets as 3-bytes bare PS/2 (data will be reported to dev3 instead dev2).
