Subject: [PATCH 04/21] ARM: topology: remove unneeded check for /cpus node
Date:   Wed,  5 Sep 2018 14:37:21 -0500
Message-Id: <20180905193738.19325-5-robh@kernel.org>
In-Reply-To: <20180905193738.19325-1-robh@kernel.org>

Precedence: bulk

Checking for "/cpus" node is not necessary as of_get_cpu_node() will fail
later on anyways. The call to of_find_node_by_path() also leaks a
reference. So just remove the check.

Please ack and I will take via the DT tree. This is dependent on the
first 2 patches.
