[patch 3/3] HID: multitouch: add support of other generic collections in hid-mt
From: Benjamin Tissoires
Date: Thu Dec 19 2013 - 11:24:09 EST
The ANTEC Touch Pad is a device which can switch from a multitouch
touchpad to a mouse. It thus presents several generic collections which
are currently ignored by hid-multitouch. Enable them by using the generic
protocol. Adding also a suffix for them depending on their application.
