commit dd2b379f071424f36f9f90ff83cb4ad058c7b6ed Author: Takashi Iwai <tiwai@suse.de> Date: Tue Oct 26 17:14:36 2010 +0100 drm/i915: Fix typo from "Enable DisplayPort Audio" Hi, while I looked through your changes in drm-intel git tree (as I've got a pressure for supporting DisplayPort audio), I stumbled on the possible bug in the commit a9756bb5b25d5d997df0c5d8c95db01292191bea Author: Zhenyu Wang <zhenyuw@linux.intel.com> Date: Sun Sep 19 13:09:06 2010 +0800 drm/i915: Enable DisplayPort audio In this commit, you changed the return value of g4x_dp_detect() to "bit", but it should be "status", I suppose.
