update:

Backporting 57078338b2e4 ("drm: fix drm_drv_uses_atomic_modeset on non
modesetting drivers.") fixed the issue. But 7e58fe2a97bc ("drm/atomic:
Use drm_drv_uses_atomic_modeset() for debugfs creation") changed the
functionality of the check. If this has to be applied, it will also
need an additional patch to keep the check same as linus tree.

But looking at the other mails now, and you have already dropped the patch.
