As a follow up, I read through the original thread before sending this
and my understanding is that this message probably shouldn't be getting
printed in the first place. I've turned on KMS, ATOMIC, STATE, and DP
debugging to see what shakes out. I have a KVM on my desk that I use to
switch
Commit 54d217406afe (drm: use mgr->dev in drm_dbg_kms in
drm_dp_add_payload_part2) appears to have been accidentially reverted as
part of commit 5aa1dfcdf0a42 (drm/mst: Refactor the flow for payload
allocation/removement).
I've been seeing NULL pointer dereferences in drm_dp_add_payload_part2
due
[Why]
Commit:
- commit 5aa1dfcdf0a4 ("drm/mst: Refactor the flow for payload
allocation/removement")
accidently overwrite the commit
- commit 54d217406afe ("drm: use mgr->dev in drm_dbg_kms in
drm_dp_add_payload_part2")
which cause regression.
[How]
Recover the original NULL fix and remove the
14 matches
