Subject: [PATCH net-next 2/2] tools: ynl-gen-c: don't require -o argument

From: Johannes Berg <johannes.berg@...el.com>

Without -o the tool currently crashes, but it's not marked
as required. The only thing we can't do without it is to
generate the correct #include for user source files, but
we can put a placeholder instead.
