drm_mode_config_reset() has a dual role: it creates the initial KMS state at probe time, and resets hardware and software state during suspend/resume cycles.
Since the two roles need different behaviors (notably for objects like drm_private_obj that must persist across suspend/resume), drm_mode_config_create_initial_state() was introduced to handle only the initial state creation at probe time. Switch to drm_mode_config_create_initial_state().
