* @dev: input device supporting MT events and finger tracking
* @num_slots: number of slots used by the device
+ * @flags: mt tasks to handle in core

* This function allocates all necessary memory for MT slot handling
* in the input device, prepares the ABS_MT_SLOT and
* ABS_MT_TRACKING_ID events for use and sets up appropriate buffers.
+ * Depending on the flags set, it also performs pointer emulation and

* May be called repeatedly. Returns -EINVAL if attempting to
