Subject: [PATCH] sparc: Convert to using %pOFn instead of device_node.name
Date:   Mon, 27 Aug 2018 20:52:08 -0500
Message-Id: <20180828015252.28511-7-robh@kernel.org>
In-Reply-To: <20180828015252.28511-1-robh@kernel.org>
References: <20180828015252.28511-1-robh@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In preparation to remove the node name pointer from struct device_node,
convert printf users to use the %pOFn format specifier.
