Subject: usbtouchscreen: support bigger iNexio touchscreens
From: Ondrej Zary <linux@xxxxxxxxxxxxxxxxxxxx>
Bigger Nexio touchscreens not only send more data but also the header
values are modified somehow. Fix the header somehow (it's a guesswork but
it works at least on one 46" touchscreen with 2.00SMS firmware) and also
increase rept_size.
