Is this a known bug? Is there a patch that fixes it? I'd be happy to
test it since it's making testing in VMs difficult right now.
Thanks,

ch to using mgr->dev instead of state->dev since "state" can be
NULL in some cases.

drm_dbg_kms(state ? state->dev : NULL, "Part 1 of payload creation for %s
failed, skipping part 2\n",
I think that would at least prevent this problem from crashing the machine.

real bug is probably in the caller of this function, which is
passing it a NULL state pointer, but this patch at least keeps my
machine from oopsing when this occurs.

essage, my proposed patch did prevent the
box from oopsing, so I'd really like to see it go in unless it's just
categorically wrong for the caller to pass down a NULL state pointer to
drm_dp_add_payload_part2.

I have a recurring problem where my workstation tries to put the monitor
to sleep, which triggers a warning down in the depths of the video card
driver. When I return to the machine the monitor is black, but not in
powersave mode and all of the windows on my desktop have been shuffled
off to the se
gt; connection and maybe individually connect them for a test if possible.

It looks like "count" probably needs to be clamped to

Changes in v5:
- add class string to each ref_tracker_dir
- auto-register debugfs file for every tracker in ref_tracker_d
urpose.
Add a new "class" string to the ref_tracker dir that describes the
the type of object (sans any individual info for that object).

This one just fixes a typo in the ref_tracker_dir_init() kerneldoc

Allow pr_ostream to also output directly to a seq_file without an
intermediate buffer. The first caller of +ref_tracker_dir_seq_print()
will come in a later patch, so mark that __maybe_unused for now. That
designation will be removed once it is used.

Now that we have dentries and the ability to create meaningful symlinks
to them, don't keep a name string in each tracker. Switch the output
format to print "class@address", and drop the name field.
Also, add a kerneldoc header for ref_tracker_dir_init().

come up with a scheme that gives these object unique names.
