From 961794a00eab03f4344b7d5e825e8e789e55da87 Mon Sep 17 00:00:00 2001 From: Ping Cheng Date: Thu, 5 Dec 2013 12:54:53 -0800 Subject: [PATCH] Input: wacom - add reporting of SW_MUTE_DEVICE events New Intuos series models added a hardware switch to turn touch data on/off. The state of the switch is reported periodically from the tablet. To report the state the driver will emit SW_MUTE_DEVICE events.
