From a3ae552b5259e6ffd8d124a9fa9923283af2828a Mon Sep 17 00:00:00 2001 From: Nicholas Bishop Date: Mon, 4 Sep 2017 15:40:42 -0400 Subject: [PATCH] HID: add multi-input quirk for IDC6680 touchscreen The Ideacom 6680 touchscreen is found in the Dell Latitude 2100. It has two USB descriptors, the first of which has two input reports. The HID_QUIRK_MULTI_INPUT quirk is needed to keep the correct maximum value for ABS_X/ABS_Y (8191 instead of 65535).
