Upd: hid-multitouch: is pen hovering ever possible?

Hello guys,

here is a 3-lines patch that made the pen working with hid-multitouch. It just delegates pen to hid-input.
Hope it helps someone.

Kind regards,
Dmitry Mastykin

Hello guys,
thanks to all of you for your great work!

Please, answer, is pen hovering ever possible using hid-multitouch driver?
If I remove hid-multitouch - hovering works well with hid-generic.
I can't unbind from hid-multitouch and bind to hid-generic: bind fails with "No such device".
I tried to modify hid-multitouch, but was not able to get hovering work using multitouch reports.
Then I noticed, that wacom uses non-multitouch reports for their pen devices, and added a quirk to hid-multitouch that changes pen's behavior to non-multitouch (patch attached). It works, but the way must be wrong(
How should one proceed in right way?

Thank you very much!
