Subject: [PATCH 08/13 linux-next] serial: sunsu: use container_of to resolve uart_sunsu_port from uart_port
Date: Sun, 5 Oct 2014 19:01:09 +0200 [thread overview]
Message-ID: <1412528475-1449-9-git-send-email-fabf@skynet.be> (raw)
In-Reply-To: <1412528475-1449-1-git-send-email-fabf@skynet.be>
Use container_of instead of casting first structure member.
