[PATCH libinput 0/3] Automatic device group assignment

[Peter Hutterer]

This patchset assigns wacom devices into the same device group. libinput
itself doesn't do the guesswork here, it's done in the udev rule through
LIBINPUT_DEVICE_GROUP. libinput just uses that value to strcmp() and
auto-assign the groups.

The udev rule is a bit of a hackjob but it does the job and I ran out of
ideas on how to do this better. In the future we could call out into a
custom binary that uses the actual phys of the device but for now this will
do.

Cheers,
  Peter
