NAME
       input_mt_init_slots - initialize MT input slots

	   input device supporting MT events and finger tracking

       num_slots
	   number of slots used by the device

       flags

DESCRIPTION
       This function allocates all necessary memory for MT slot handling in
       the input device, prepares the ABS_MT_SLOT and ABS_MT_TRACKING_ID
