Subject: [PATCH] PCI: Use of_node_name_eq for node name comparisons
Date: Wed, 5 Dec 2018 13:50:34 -0600 [thread overview]
Message-ID: <20181205195050.4759-18-robh@kernel.org> (raw)
Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.
