Subject: [PATCH 6/8] sparc: Use of_node_name_eq for node name comparisons
Date: Wed,  7 Nov 2018 16:31:49 -0600	[thread overview]
Message-ID: <20181107223151.14991-7-robh@kernel.org> (raw)
In-Reply-To: <20181107223151.14991-1-robh@kernel.org>

Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.
