[PATCH 0/6] Remove all bad dp_mst_port uses and hide struct def
So we don't ever have to worry about drivers touching drm_dp_mst_port
structs without verifying them and crashing again.
Lyude Paul (6):
drm/dp_mst: Add drm_dp_get_payload_info()
drm/nouveau: Use drm_dp_get_payload_info() for getting payload/vcpi
drm/nouveau: Stop reading port->mgr in nv50_mstc_get_modes()
drm/nouveau: Stop reading port->mgr in nv50_mstc_detect()
drm/dp_mst:

[PATCH v5 06/14] drm/dp_mst: Protect drm_dp_mst_port members with locking
...e of (emphasis on "that
we're aware of"): locking.
When we go through and probe the link addresses and path resources in a
topology, we hold no locks when updating ports with said information. The
members I'm referring to in particular are:
- ldps
- ddps
- mcs
- pdt
- dpcd_rev
- num_sdp_streams
- num_sdp_stream_sinks
- available_pbn
- input
- connector
Now that we're handling UP requests asynchronously and will be using some of
the struct members mentioned above in atomic modesetting in the future for
features such as PBN validation, this is going to become a lot more important.
As...

[PATCH v5 00/14] DP MST Refactors + debugging tools + suspend/resume reprobing
This is the final portion of the large series for adding MST
suspend/resume reprobing that I've been working on for quite a while
now. In addition, I:
* Refactored and cleaned up any code I ended up digging through in the
process of understanding how some parts of these helpers worked.
* Added some debugging tools along the way that I ended up needing to
figure out some issues in my own
