From fc55e95214f1e8384e48cff88279d16507fa5358 Mon Sep 17 00:00:00 2001 From: Anssi Hannula Date: Thu, 3 Apr 2008 16:18:44 -0400 Subject: [PATCH] Input: xpad - do not report nonexistent buttons for xbox360 The buttons BTN_C and BTN_Z are only used in the original xbox controller, not in xbox360 controller. Therefore only add them to keybit when the controller is a non-360 one.
