It actually is, virNodeDevCapMdevFree uses is, and it also used in the snippet
below. Anyhow, I usually try to introduce concepts, data types and other
symbols first to make it a tiny bit easier for the reviewer, since this can
be easily missed when actually implementing function bodies, or logic in
general. I have no problem with moving everything related to the structure to
the following patch. Although in that case, if this patch would still be worth
having as separate or more-or-less merge it with the next one completely. Let
me know, what you find as the most plausible solution for you.
