The race condition between fbcon and drm_panic can only occurs if VT_CONSOLE is set. So update drm_panic dependency accordingly. This will make it easier for Linux distributions to enable drm_panic by disabling VT_CONSOLE, and keeping fbcon terminal. The only drawback is that fbcon won't display the boot kmsg, so it should rely on userspace to do that.

2024-06-17drm: zynqmp_kms: Fix AUX bus not getting unregisteredSean Anderson
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?

Unconditionally enable the DPSUB layer in the corresponding atomic plane update callback. Setting the new display mode may require disabling and re-enabling the CRTC. This effectively resets DPSUB to the default state with all layers disabled. The original implementation of the plane atomic update enables the corresponding DPSUB layer only if the framebuffer format has changed. This would leave the layer disabled after switching to a different display mode with the same framebuffer format.
