Any feedback, please?

Trying to get this one upstreamed for four months already and hope to
get it to 5.2.

Any news on this? It has been waiting for review for a while. Is there
someone else who could review this?

I don't see any of these patches applied in linux-next nor 5.2-rc1.

What is the issue here?

The patch is in drm-misc-next and should show up in linux-next tomorrow.

My understanding is that somebody needs to push drm-misc-next after each
-rc1 release before drm-misc-next feeds into linux-next. Chances of that
happening between -rc1 and the linux-next release the day after are
fairly small.
