The patch is also available via 'lore' here:
https://lore.kernel.org/all/20221020034809.506525-1-alexander.deuc...@amd.com/
I'd like to add that the two patches did not work for me either (Ryzen 7
PRO 4750U). After patching the source, I built and installed the
5.10.0-19 kernel, but it did not help at all, after some hardware inits,
the display input was suddenly gone and I had to do a forced shutdown again.
The last lines from /var/log/kern.log before it froze:
Oct 20 16:41:43 tasha kernel: [ 10.742172] amdgpu 0000:07:00.0:

Oct 20 16:41:43 tasha kernel: [ 10.742250] amdgpu 0000:07:00.0:
amdgpu: amdgpu: finishing device.
Afterwards, I booted my freshly built 5.10.0-19 kernel with "nomodeset"
and was able to log in via X, but the two displays attached to my laptop
did not work, only my internal panel.
I hope this helps, if there's something additional I could contribute,
please let me know!
Best regards
