Hey Evan,

I've been having an issue with uploading `pp_table`s on recent
`amd-staging-drm-next` kernels. I bisected the issue, and it came back
to a commit of yours - ec8ee23f610578c71885a36ddfcf58d35cccab67.

I didn't have your gitlab handle to CC you on the issue, so I thought
I'd at least alert you to it.

Here's a link to the issue on GitLab:
https://gitlab.freedesktop.org/drm/amd/-/issues/1243

I'd appreciate any help or insight you could offer here as I work on a
fix.
