I believe you either have the ifdef and the of_match_ptr(), or you have
neither. The use of of_match_ptr() is required when you wrap the
struct/array in an ifdef, so that the struct/array is only referenced
when it's declared.

I guess from your response you want the struct/array wrapped in an
ifdef, and to use of_match_ptr() when referencing it. I'll go ahead with
that; no need to reply if that's what you meant.
