Subject: [PATCH 0/6] Fix legacy DPMS changes with MST

There's two major things this patchset does:
 - Add drm_dp_mst_connector_atomic_check() so drivers don't need to use
   ->best_encoder() to prevent modesets on zombie MST connectors. We'll
   use this later for implementing MST fallback retraining as well.
 - Fix DPMS on->off changes failing with legacy modesetting users after
   an MST connector's topology has disappeared, which resulted in CRTCs
   being left on when they shouldn't have been

Lyude Paul (6):
  drm/dp_mst: Introduce drm_dp_mst_connector_atomic_check()
  drm/nouveau: Unbreak nv50_mstc->best_encoder()
  drm/i915: Leave intel_conn->mst_port set, use mst_port_gone instead
  drm/i915: Skip vcpi allocation for MSTB ports that are gone
  drm/i915: Fix intel_dp_mst_best_encoder()
  drm/amdgpu/dm/mst: Use drm_dp_mst_connector_atomic_check()
