Comment 21 for bug 2002467

Hi Paul,

Aaron has found the bad commit which is
224dffc89a957 drm/amdgpu: make sure to init common IP before gmc

I've updated the test kernel at the same location which reverted the commit.

I'm going to submit SRU to revert this one, please help to verify it, thanks.
