From 58b939959d228681208ba997595411fddc860849 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Mon, 8 Mar 2010 22:37:10 -0800 Subject: Input: scancode in get/set_keycodes should be unsigned MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The HID layer has some scan codes of the form 0xffbc0000 for logitech devices which do not work if scancode is typed as signed int, so we need to switch to unsigned it instead. While at it keycode being signed does not make much sense either.
