This is also causing log spam on 5.15. It was included in 5.15.128 as commit 4921792e04f2125b5eadef9dbe9417a8354c7eff. I encountered this and found https://gitlab.freedesktop.org/drm/amd/-/issues/2820 while researching the problem.

[PATCH AUTOSEL 5.10 13/22] drm/amdgpu: install stub fence into potential unused fence pointers

From: Lang Yu [ Upstream commit 187916e6ed9d0c3b3abc27429f7a5f8c936bd1f0 ] When using cpu to update page tables, vm update fences are unused. Install stub fence into these fence pointers instead of NULL to avoid NULL dereference when calling dma_fence_wait() on them. Suggested-by: Christian Kön
