It's not really clear to me what branch it should be pulled in? is it
for drm-misc-next?

JFYI - the wrapping was because of evolution, sorry about that. Going to make
sure that gets fixed the next time I have to send out a topic branch

Fixed manually, but I can't pull this into drm-intel-next directly after
all, because the baseline is not in drm-intel-next history. The diffstat
for drm-intel-next is:

65 files changed, 3656 insertions(+), 780 deletions(-)

I asked for this to be a topic branch so I could pull it into
drm-intel-next. I guess I'll just have to do a drm-next backmerge
instead.

I'm curious, how did you generate and send this pull request? The lines
are wrapped with newlines, and you have non-breaking spaces instead of
regular spaces there.

So for me this fails with:

Pulling   git://anongit.freedesktop.org/drm/drm-misc tags/topic/amdgpu-dp2.0-mst-2021- 10-27 ...
fatal: invalid refspec 'git://anongit.freedesktop.org/drm/drm-misc'
