From 6245bde29dd049300d663516398335be8d451b78 Mon Sep 17 00:00:00 2001 From: Przemo Firszt Date: Tue, 28 Feb 2012 17:19:05 +0000 Subject: HID: wacom: Add pad buttons reporting on Intuos4 WL MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds reporting of 1 wheel button and 8 strip buttons for Intuos4 WL. The buttons are reported as BTN_0 to BTN_9. The change of type butstate variable is required as the old type 'char' couldn't store state of 9 buttons. The change is not affecting Graphire tablet as it only uses first 2 bits of 'butstate'.
