Subject: [PATCH 3/4] connector: use 'size' everywhere in cn_netlink_send()
Date: Mon, 30 Sep 2013 22:03:08 +0200	[thread overview]
Message-ID: <1380571389-15343-4-git-send-email-minipli@googlemail.com> (raw)
In-Reply-To: <1380571389-15343-1-git-send-email-minipli@googlemail.com>

We calculated the size for the netlink message buffer as size. Use size
in the memcpy() call as well instead of recalculating it.
