(In case there was a misunderstanding here, I meant that some
parentheses can be removed without affecting correctness:

#define NT_INIT(buf, type, desc) \
	nt_init_name(buf, NT_ ## type, &(desc), sizeof(desc), NN_ ## type))

It still doesn't matter though -- and some people do prefer to be
defensive anyway and err on the side of having too many parentheses
rather than too few.)
