See drm_drv.c for the code example. Not sure if I understood your comment here. The drm_drv.c example also calls drm_dev_register(). The only difference is that it calls it inside driver_probe(), while on this driver, it uses: static const struct component_master_ops kirin_drm_ops = { .bind = kirin_drm_bind, .unbind = kirin_drm_unbind, }; static int kirin_drm_platform_probe(struct platform_device *pdev) { ... drm_of_component_match_add(dev, &match, compare_of, remote); ... return component_master_add_with_match(dev, &kirin_drm_ops, match); } Are you meaning that I should get rid of this component API and call kirin_drm_bind() from kirin_drm_platform_probe()?
