Keeping the file as-is helps apply newer patches easily on top as opposed to redoing the changes. I would prefer not to move to ARRAY_SIZE and stick to what's already in the file. Balbir Singh.

Thanks but no thanks on this one Colin. Is there a checkpatch blacklist anywhere? So we don't keep discovering things in this file that need to be fixed? cheers

What might be useful is a generic marker somewhere in a file that shows the file as a generated file and indicates the file should not otherwise be modified.
