We were using the same force-poweron bit in the two codepaths, so they
could race to have one of them lose GPU power early.

You can add:
Fixes: 4b565ca5a2cb ("drm/msm: Add A6XX device support")

I only pointed it at 5.9 because it looked like it would probably

Fair enough. It is a good bug to fix but not if there are a lot of conflicts to
deal with.
