From 64ba3a5f0cdf97cec003d88557a3d210c1ad1ef7 Mon Sep 17 00:00:00 2001 From: Aristeu Rozanski Date: Wed, 22 Jun 2011 01:17:17 -0700 Subject: [PATCH] Input: wacom - use only one interface with DTU-2231 The Wacom DTU-2231 tablet has two interfaces on its default configuration and both have HID class, leading to the creation of two input devices instead of one. Only the first one is used, so filter out the second.
