Subject: [PATCH v6 4/8] of: Reduce indentation in of_graph_get_next_endpoint
Date: Wed, 5 Mar 2014 10:20:38 +0100 [thread overview]
Message-ID: <1394011242-16783-5-git-send-email-p.zabel@pengutronix.de> (raw)
In-Reply-To: <1394011242-16783-1-git-send-email-p.zabel@pengutronix.de>
A 'return endpoint;' at the end of the (!prev) case allows to
reduce the indentation level of the (prev) case.
