Ville Syrjälä d14e7b6d1d drm/i915: Check DP link status on long hpd too ... We are no longer checkling the DP link status on long hpd. We used to do that from the .hot_plug() handler, but it was removed when MST got introduced. If there's no userspace we now fail to retrain the link if the sink power is toggled (or cable yanked and replugged), meaning the user is left staring at a blank screen. With the retraining put back that should be fixed. Also remove the leftover comment that referred to the old retraining from .hot_plug(). Fixes a regression introduced in: commit 0e32b39cee Author: Dave Airlie <airlied@redhat.com> Date: Fri May 2 14:02:48 2014 +1000 drm/i915: add DP 1.2 MST support (v0.7) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=89453 Tested-by: Palmer Dabbelt <palmer@dabbelt.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=91407 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=89461 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=89594 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=85641 Cc: Dave Airlie <airlied@redhat.com> Cc: stable@vger.kernel.org Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com>		2015-08-31 18:16:43 +03:00
