No, the patch is fine I think, I was just double checking it and noticed that nobody really marks CLOCKSOURCE_OF_DECLARE() as __initdata in practice. > Let me look in details. might not be worth doing, and it will quickly bitrot anyway, as new drivers might not pick it up. Plus, should that structure ever get modularized, it will have to be removed again.
