Can you please look at doing > that as a regular init call setup? I strongly disagree with using init calls for this kind of thing. There are ordering dependencies between the initialization code that can only be sanely managed by explicitly calling functions in a particular order; there's simply no way to manage this using initcalls. This is exactly why the hooks in the ARM machine descriptors exist...
