Cover letter [PATCH 0/2] 6.12 and below: amdgpu: fix panic with SI and DC

The first commit is needed for the second one to be reverted cleanly.

The second breaks DC support on my AMD 7750. Kernel panics and I get a black screen on boot. With these two reverted, 6.12 is usable again.

Tried to git cherry-pick the fixes but that proved to be difficult to do cleanly.

I see 6.6 also has these two commits.

Not sure what the proper procedure is to request reverts on stable kernels.
