This, and the cleanup dance you have to do in patch 5/8, are my only
gripes with the series. I would prefer it if crtc->name and plane->name
were managed dynamically by the init/cleanup functions like
connector->name and encoder->name are. However those are easier because
the caller doesn't decide the name.

Do you think it would be too ugly to have this here:

	crtc->name = kstrdup(crtc->name ? crtc->name : "", GFP_KERNEL);

It would of course be neater if the name was passed in as parameter, but
that would generate quite a bit of unnecessary churn.

If you are all "meh" I guess I can live with your approach too.

BR,
Jani.
