History
Alexandre Hamamdjian ad1d940efb Input: edt-ft5x06 - ignore contacts with an out-of-range slot id 
The per-contact slot id is taken from the top nibble of the third
report byte, so it can be any value from 0 to 15. The driver only
allocates max_support_points MT slots (2 to 10 depending on the
variant), so a report that carries an id at or above that count - be it
a genuinely higher-numbered contact or a corrupted byte - is outside the
range the input core was told about.

input_mt_slot() silently ignores an ABS_MT_SLOT beyond num_slots and
leaves the current slot unchanged, so the following
input_mt_report_slot_state()/touchscreen_report_pos() pair is applied to
whichever slot happened to be selected last, reporting the contact at the
wrong position. Skip such entries instead.
