[PATCH 00/25] Support of Nexio 42" and new default class for hid-multitouch

[Benjamin Tissoires]

Hi guys,

finally, I managed to send a new bunch of patches. Sorry for the delay from the
previous version, but meanwhile, I implemented an automatic regressions tests
for hid device [1].
So this series seems pretty big, but it does not break any known devices (I ran
40 successful tests for this series)[2].

To sum up:
- Nexio devices were problematic in the sense they use out of range values for
some of the fields, and consider that the driver won't treat the extra touches
based on the reported contact count.
- fortunately, this behavior (relying on contact count) is compatible with all
the devices I know, which leads to think that this is how the Windows 7/8 driver
manage to handle such a different bunch of devices.
- thanks to the automatic testing, I was able to fix broken devices
(Sharp LC-20FE1-W screen 04dd:9681, Sitronix 1403:5001 and Cando 2087:0a02)
and optimize many others. In order to allow a bisection to be done, I split
the patches in many different ones, one per device type.
- finally, I changed the default class in order to handle the new devices in a
better way.

Cheers,
Benjamin
