From ed7145ed0fc38dc9c1640c01d75de5baade335cc Mon Sep 17 00:00:00 2001

Subject: [PATCH 0576/4131] drm/amd/display: Create dm_atomic_state
We really want to use the new private_atomic_state but can't right now
as we have to maintain some backward compatibility to older kernels. For
now let's follow Intel's approach and extend the drm_atomic_state.
