This driver contains too much code. I am wondering if the device actually
supports tracking id, or whether it is emulated in the driver code? If tracking
is not well supported in hardware, then please use MT protocol A and remove the
usage of ABS_MT_TRACKING_ID and the logic around it. If tracking is indeed well
supported in the hardware, then please use MT protocol B.

Thanks,
Henrik
