Subject: [PATCH 12/13 linux-next] serial: use container_of to resolve uart_sunzilog_port from uart_port
Date: Sun,  5 Oct 2014 19:19:48 +0200	[thread overview]
Message-ID: <1412529589-1753-3-git-send-email-fabf@skynet.be> (raw)
In-Reply-To: <1412529589-1753-1-git-send-email-fabf@skynet.be>

Use container_of instead of casting first structure member.
