From a7189f6ff59bd8c2ffd6780c06b6da060d1ed02f Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 19 Apr 2012 15:42:58 +0100 Subject: [PATCH] drm/radeon: fix load detect on rn50 with hardcoded EDIDs. BugLink: http://bugs.launchpad.net/bugs/987337 commit a09d431f344d854e4fe9cfac44f78cb8202f3eb7 upstream. When the force changes went in back in 3.3.0, we ended up returning disconnected in the !force case, and the connected in when forced, as it hit the hardcoded check. Fix it so all exits go via the hardcoded check and stop spurious modesets on platforms with hardcoded EDIDs.
