Since 5.12-rc2, my Dell XPS-15 laptop has had a blank screen on boot.
The system seems to run fine other than having no display, I am able
to ssh into the machine. I don't see anything interesting in the dmesg
log. I bisected the problem down to this commit, and reverting it fixes
the problem.

Have you tried with drm-tip? It has acca7762eb71bc0 which hopefully helps here.
