Subject: [PATCH 10/21] openrisc: use for_each_of_cpu_node iterator
Date:   Wed,  5 Sep 2018 14:37:27 -0500
Message-Id: <20180905193738.19325-11-robh@kernel.org>
In-Reply-To: <20180905193738.19325-1-robh@kernel.org>
References: <20180905193738.19325-1-robh@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use the for_each_of_cpu_node iterator to iterate over cpu nodes. This
has the side effect of defaulting to iterating using "cpu" node names in
preference to the deprecated (for FDT) device_type == "cpu".

This also fixes a leaked reference for cpus node.
