Sean Anderson c6ad6096f9 drm: zynqmp_kms: Fix AUX bus not getting unregistered ... [ Upstream commit 0743dafefd ] drm_encoder_cleanup is responsible for calling drm_bridge_detach for each bridge attached to the encoder. zynqmp_dp_bridge_detach is in turn responsible for unregistering the AUX bus. However, we never ended up calling drm_encoder_cleanup in the remove or error paths, so the AUX bus would stick around after the rest of the driver had been removed. I don't really understand why drm_mode_config_cleanup doesn't call drm_encoder_cleanup for us. It will call destroy (which for simple_encoder is drm_encoder_cleanup) on encoders in the mode_config's encoder_list. Should drm_encoder_cleanup get called before or after drm_atomic_helper_shutdown?
