This has been tested on a Dell Latitude E6400, where the DualPoint Stick reports bare packets, which get reported via dev3 when the touchpad is idle, and via dev2 when the touchpad and stick are used simultaneously. This commit fixes this inconsistency by always reporting bare packets via dev3. Note that since the come from a DualPoint Stick they really should be reported via dev2, this gets fixed in a later commit.

Note that since there is no way to distinguish these packets from an external PS/2 mouse (insofar as these laptops have an external PS/2 port) this means that we will be reporting PS/2 mouse events via this evdev node too, as we've been doing in kernel 3.19 and older. This has been tested on a Dell Latitude D620 and a Dell Latitude E6400, which both have a V2 touchpad + a DualPoint Stick which reports bare packets.
