[PATCH v2 0/9] Support of Nexio 42" and new default class for hid-multitouch

Hi guys,

so, this is the v2 of the support of win7/8 devices.

changes since v1:
- removed the "optimization" patches, as the benefit was minimum
- introduce a new callback "report" in hid-core that drivers can use to treat the
  report by having it entirely parsed
- rely on this new hook to support Nexio 42"

side notes:
- I've tested removing the heavy call to kzalloc in hid_input_field. The results
  are disapointing -> the processing time remains the same.
- I've also tested not to rely on .event hook in hid-multitouch but only on .report.
  Idem, I thought it would reduce the code of hid-multitouch and will enhance its
  processing time, but the results are a roughly same number of lines for hid-multitouch
  and the same processing time... :(
- these 2 tests helped in cleaning the patch set from the last time.

And again, finally, I've pass all the 40 regression tests of my db. \o/

Cheers,
Benjamin
