What tree did you use to generate the patch? On amd-staging-drm-next,
MaxPrefetchMode is 0 for the second last branch, which is the correct
one, so this patch isnt needed.
I'm using the stable tree, sorry, if it is out of
date just ignore it then.
Thanks!
José.
Actually, you're right - the patch's limited context mislead me, sorry.
But please add the following tag and sent it to stable@xxxxxxxxxxxxxxx
instead:
Fixes: 974ce181 ("drm/amd/display: Add check for PState change in DCN32")
