The contact id is semantically equivalent to ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates the driver. The situation can be improved upon by providing a common pointer emulation code, thereby removing the need for the tracking id in the driver. This patch moves all tracking event handling over to the input core, simplifying both the existing drivers and the ones currently in preparation.
