libinput - Wacom Intuos PT S 2 Finger

[g]

Hello, I've just received the tablet mentioned above. I've tried to get
it up and running with libinput-gestures. When starting gestures I get
the following error:

libinput error: libinput bug: Device 'Wacom Intuos PT S 2 Pad' does not
meet tablet criteria. Ignoring this device.

I guess it's just unknown to libinput. If somebody can point me to the
right place in code I will submit a patch.

Regards
Goran
