Subject: string-util: use size_t for strjoina macro (#6914)
X-Git-Tag: v235~64
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=35207e259ef44f62faf71acc4bbc7d43311a4583;p=platform%2Fupstream%2Fsystemd.git

string-util: use size_t for strjoina macro (#6914)

`strlen` returns a `size_t` and `alloca` expects a `size_t`.
