Except when clock recovery fails too hard and we restart with channel eq training. Which doesn't make a lot of sense really, since just stopping/restarting the DP port at this point violates the modeset sequence documented in the Bspec. So let's tempt fate and try this. This patch is motivated by a WARN_ON triggered by commit bc76e320f21f8bd790a72bd5dc06909617432352 Author: Daniel Vetter Date: Tue May 20 22:46:50 2014 +0200 drm/i915: Drop now misleading DDI comment from dp_link_down References: https://bugs.freedesktop.org/show_bug.cgi?id=85670 Signed-off-by: Daniel Vetter Acked-by: Jani Nikula Signed-off-by: Daniel Vetter --- Reading git-diff-tree failed
