[PATCH v6 0/6] drm/dp_mst: Improve VCPI helpers, use in nouveau

[Lyude Paul <lyude@redhat.com>]

This patchset does some cleaning up of the atomic VCPI helpers for MST,
and converts nouveau over to using them. I would have included amdgpu in
this patch as well, but at the moment moving them over to the atomic
helpers is nontrivial.

[sorry for still not adding your R-Bs! I ended up needing to make a
lot of changes to make it so we do actually kref() each port in the
atomic state]

Lyude Paul (6):
  drm/dp_mst: Add some atomic state iterator macros
  drm/dp_mst: Return kref_put() result from drm_dp_put_port()
  drm/dp_mst: Start tracking per-port VCPI allocations
  drm/dp_mst: Check payload count in drm_dp_mst_atomic_check()
  drm/nouveau: Stop unsetting mstc->port, check connector registration
  drm/nouveau: Use atomic VCPI helpers for MST
