It is misleading to use "dev" to mean a functional resource. And in adopting the Linux Driver Model, struct nubus_board will embed a struct device. Drivers will then bind with boards, not with functional resources. Rename struct nubus_dev as struct nubus_functional_resource. This is the vendor's terminology and avoids confusion.Isn't "struct nubus_functional_resource" a bit long?
Right.
What about "nubus_res"? "nubus_fres"?
I think the temporary variables can remain 'fres', as that's just a mnemonic, though the declaration really ought to tell us something meaningful. You and I both avoided 'func' as an abbreviation. I think it suggests a 'C' function pointer. And 'res' and 'rsrc' suggest an ioport.h struct resource. An unambiguous compromise would be 'nubus_functional_rsrc' but maybe this is still too long? Perhaps 'struct nubus_rsrc' or 'struct nubus_res' are okay if we can keep the distinction between 'functional resources', 'slot resources' and 'board resources' clear by naming instances appropriately? E.g.
