There's CONFIG_DRM_PANEL=y # CONFIG_OF is not set but __devm_drm_panel_alloc is inside #ifdef CONFIG_OF. I don't know that it should be. There are some stubs in drm_panel.h for !CONFIG_OF but not this one. Finally, DRM_PANEL_AUO_A030JTN01 does not depend on OF. That's the issue, but I don't know what the correct fix would be.
