The configuration of_node is there to override the device one if there were some reason to do it. This should only happen in a situation where we weren't able to use the core parsing, with modern drivers it indicates a problematic binding so the code deliberately doesn't handle it. Anything with a problematic binding will have generated the init_data in driver code anyway. If we come up with a reason to extend the interface we can do that but for now there is no need.

Line number references are complately unhelpful if you don't say what you're looking at (for me that's a call to irq_find_mapping() which I'm guessing isn't what you were talking about).

No, they both do the same thing. [unhandled content-type:application/pgp-signature] | |
