I'm not aware of any currently-upstream code that will hit this [1]. I've hit it in out-of-tree code (or, code that I submitted to dri-devel, but wasn't accepted as-is), and this is the "belt and braces" part -- the primary fix is that we should avoid calling things like drm_atomic_get_crtc_state() at inappropriate times.
So, is the "extra safety" check really something that should go to -stable? (Because let's be honest, everything with a Fixes tag goes there.) Maybe?
Anyway, if you want to "blame" anything, this commit actually dropped the safety check:

[1] But I'm not omniscient. So maybe it's good to have anyway.
