From c653daba895a2d339b3b8f04e69fc111443ef327 Mon Sep 17 00:00:00 2001 From: Przemo Firszt Date: Fri, 4 May 2012 18:00:10 +0100 Subject: [PATCH] HID: wacom: Add tilt reporting for Intuos4 WL Tile is reported to input subsystem as reported by the device without any modifications. It means that tilt X/Y range is 0 to 127 and it's not centered on zero.
