5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Armin Wolf W_Armin@gmx.de
This reverts commit 56b522f4668167096a50c39446d6263c96219f5f.
A user reported that this commit breaks the integrated gpu of his notebook, causing a black screen. He was able to bisect the problematic commit and verified that by reverting it the notebook works again. He also confirmed that kernel 6.8.1 also works on his device, so the upstream commit itself seems to be ok.
An amdgpu developer (Alex Deucher) confirmed that this patch should have never been ported to 5.15 in the first place, so revert this commit from the 5.15 stable series.
