Subject: [PATCH 2/3] HID: multitouch: remove pen special handling
Pens have a special handling in hid-mt as hybrid pen/touch devices
are quite common now. However, some fancy devices presents also
useful collections like mouse or keyboard.
The special case for the pen may not be a special case, and treat it as
a generic case.
