I hardly expected more OF_DECLARE macros when I opened this up. Given desires to get rid of them, I don't think adding to it is the way forward. That wrapping a platform driver around OF_DECLARE looks pretty horrible IMO. I browsed some of the discussion around this. It didn't seem like it's a large number of drivers that have to be fixed to defer probe correctly. Am I missing something? I'd rather keep the pressure on getting fw_devlink on by default. Rob
