Hey,

I ran these changes in kernels w/ and w/o atomic async flip support and
w/ and w/o overlay async flip support. I found some problems, mainly in
the way the test handles failures, but also with overlay async support,
overlay-atomic skips when running in the `kms_async_flip` subtest
sequence.

I tested with Cezanne DCN2.1 with Debian and amd-staging-drm-next branch
with your overlay async patches on top (kernel w/ overlay async), kernel
from distro (kernel w/ atomic asycn w/o overlay async) and mainline 6.6.
