A regression was bisected to this commit:

https://bugzilla.kernel.org/show_bug.cgi?id=115321

So it's probably better to hold off on backporting this commit (and
possibly the corresponding amdgpu commit as well).

Why not just provide stable with the bugfix as well? Being
bug-compatible is a big plus :)

What bugfix are you referring to? I'm not aware of any fix for this
regression.

FYI, the backport to 4.5 triggered another bug report:
