Subject: [PATCH v2 0/4] drm/dp_mst: Fix regressions from new atomic VCPI helpers

This fixes the extra issues I discovered upstream after the introduction
of my rework of the atomic VCPI helpers that occur during
suspend/resume.

This time around, we use a slightly different but much less complicated
approach for fixing said issues.

Lyude Paul (4):
  drm/dp_mst: Fix unbalanced malloc ref in drm_dp_mst_deallocate_vcpi()
  drm/dp_mst: Remove port validation in drm_dp_atomic_find_vcpi_slots()
  drm/atomic: Add drm_atomic_state->duplicated
  drm/nouveau: Move PBN and VCPI allocation into nv50_head_atom
