4.18-stable review patch. If anyone has any objections, please let me know.
------------------ From: Lyude Paul <ly...@redhat.com> commit 3c499ea0c662e2f38aafbd4f516b08aab8cfa0e5 upstream. As pointed out by Daniel Vetter, we should be usinng drm_drv_uses_atomic_modeset() for determining whether or not we want to make the debugfs nodes for atomic instead of checking DRIVER_ATOMIC, as the former isn't an accurate representation of whether or not the driver is actually using atomic modesetting internally (even though it might not be exposing atomic capabilities).
