[Intel-gfx] [PATCH 4/4] drm/i915: don't try to retrain a DP link on an inactive CRTC

Atm we may retrain the DP link even if the CRTC is inactive through HPD work-intel_dp_check_link_status(). This in turn can lock up the PHY (at least on BYT), since the DP port is disabled. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=81948 Signed-off-by: Imre Deak imre.d...@intel.com
