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

Hi guys,

Ok, this patch series is not very consistent and could have been split in two...
Anyway, here is some work for hid-multitouch:

- 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!)

Happy reviewing.

Cheers,
Benjamin

PS: it might be Spring coming, but I am definitively trying to reduce the total
lines of code in the HID subsystem...

Benjamin Tissoires (3):
  HID: multitouch: remove default behaviors
  HID: multitouch: remove pen special handling
  HID: multitouch: add support of other generic collections in hid-mt
