No need for a home-grown version, the generic helper should work just
fine.  It also handles vgacon removal these days, see commit
1c74ca7a1a9a ("drm/fb-helper: call vga_remove_vgacon automatically."),
so that can be removed too.

I think I'd still wait until 5.4-rc1 with merging this one, just to give
another full release and people to test it before we pull the trigger.
Overabundance of caution and all that.

Thanks a lot for doing this!

Whole series or just the i915 patch?

Ok I just checked and this all landed in 5.1 already, I thought it was
more recent. I think that's good enough, push it all without more
waiting.

After-the-fact nitpick: i915 maintainers were Cc'd on the original
patch, but not on the subsequent discussion on merging, or where to
merge. intel-gfx@ mailing list wasn't Cc'd at all, which means this
didn't get any pre-merge CI coverage we expect on every patch. I found
about this having been merged through a merge conflict.

If you don't see the ack from the maintainers, please ask.


BR,
Jani.
