Subject: [PATCH 01/29] of: unflatten: allocate root node explicitly
Date: Tue, 26 Feb 2013 21:18:28 +0100	[thread overview]
Message-ID: <1361909936-2665-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1361909936-2665-1-git-send-email-s.hauer@pengutronix.de>

By doing so of_new_node does not depend on the global root_node
anymore.
