Re: [PATCH 0/3] HID: multitouch cleanups and support for fancy devices

- the first patch is mainly a way for us to reduce the work load regarding hid-mt
  when device makers ask for an inclusion in the kernel.
  Also, I have been notified that a Quanta 3008 was not working, and it occurs
  that this particular device has a special handling in hid-mt. Of course, the
  hardware maker reused the same VID/PID, but changed the protocol.
  So yes, I am in favour of killing all unneeded special cases.

  I checked all the devices I was able to test, and this leaves us a bunch of
  devices which, I am sure, could be removed too (all the ones following
  MT_CLS_NSMU should be in this case). So, if anyone else wants to join me in
  this crusade, I'd be glad to receive patches.

- the second and third patch are the v2 of the series I sent back in December
  2013 ([PATCH 0/3] Change in handling different input device in hid-multitouch).
  Henrik made valuable comments, and I did not had the time to look at it and to
  figure out how to address them. Now I got a different look at this work, and
  I think I addressed the issues (no more function pointers, yeah!)
