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()?
Thanks,
Mauro
