I believe it's one of those cases that the same commit landed twice. So 
the wrong SHA got added to the fixes tag.

This is the one it should have been:

1ca67aba8d11 ("drm/amd/display: only accept async flips for fast updates")

>> a7c0cad0dc06 ("drm/amd/display: ensure async flips are only accepted for

Thanks!

Seeing the correct sha1; I find the problematic one backported to:

* 6.4.7 as cd013a58cf64 ("drm/amd/display: only accept async flips for 
fast updates")

and

* 6.1.42 as 438542074174 ("drm/amd/display: only accept async flips for 
fast updates")

Did you only queue for 6.5.y?  If so, can you please add to 6.1.y and 
6.4.y as well?

Thanks!
