Avoid erroneously handling two touchpoints in the same slot
If a slot's ABS_MT_TRACKING_ID event was received during SYN_DROPPED, the
driver isn't aware that a touchpoint has started or ended in that slot. When
the next ABS_MT_TRACKING_ID event arrives, the driver would unconditionally
close or open a new touchpoint. This could lead to two or more touchpoints
being opened in the same slot, the first of which is never terminated.
Or it could lead to a touchpoint being terminated that was never opened.
The event sequences that trigger this are:
ABS_MT_TRACKING_ID 83
ABS_MT_TRACKING_ID -1
SYN_DROPPED // new touchpoint started here
ABS_MT_TRACKING_ID -1
and
ABS_MT_TRACKING_ID 83
SYN_DROPPED // touchpoint ended here
ABS_MT_TRACKING_ID 84
ABS_MT_TRACKING_ID -1
We don't properly handle SYN_DROPPED, but we can avoid this by only
starting a
new touchpoint when we transition between -1 and a valid tracking ID.
