[PATCH v5 00/10] Implement proper MST fallback retraining in i915
Latest version of https://patchwork.freedesktop.org/series/39642/ ,
hopefully patchwork understands this and doesn't break anything!
Lots of changes.
Lyude Paul (10):
drm/atomic: Print debug message on atomic check failure
drm/i915: Move DP modeset retry work into intel_dp
drm/dp_mst: Fix naming on drm_atomic_get_mst_topology_state()
drm/dp_mst: Remove all evil duplicate state

[PATCH v6 00/10] drm/i915: Implement proper fallback training for MST
Latest version of PW series 39642, hopefully this should also actually
come up on intel-gfx and go through CI.
No changes other than rebasing to the current drm-intel-next-queued

Next version of https://patchwork.freedesktop.org/series/41576/
Only changes are removing duplicate SoBs that git send-email annoyingly
added. Sorry about that :(

All changes in this patch series are just to make checkpatch a little
happier, no functional changes.

[PATCH v2 0/4] drm/dp_mst: Add DP MST debugfs nodes for all drivers
...ically create debugfs nodes for drivers with MST topologies. This
was originally intended just for nouveau, but has since been expanded to
all DRM drivers.

- Fix documentation error that got noticed by the kbuild bot in
