Subject: [PATCH] Use MOVE_ARRAY
Date: Mon, 22 Jan 2018 18:50:09 +0100 [thread overview]
Message-ID: <20180122175009.20178-1-szeder.dev@gmail.com> (raw)
In-Reply-To: <d81743e5-d5ba-a565-23f7-072007493499@web.de>
Use the helper macro MOVE_ARRAY to move arrays. This is shorter and
safer, as it automatically infers the size of elements.
Patch generated by Coccinelle and contrib/coccinelle/array.cocci in
Travis CI's static analysis build job.
