When converting to atomic the state reset was done by directly calling the functions, and before the modeset object was fully initialized. This means the various ->dev pointers weren't set up.
After commit 51f644b40b4b794b28b982fdd5d0dd8ee63f9272 Author: Daniel Vetter <[email protected]> Date: Fri Jun 12 18:00:49 2020 +0200 drm/atomic-helper: reset vblank on crtc reset this started to oops because now we're trying to derefence drm_crtc->dev. Fix this up by entirely switching over to drm_mode_config_reset, called once everything is set up.
