From mboxrd@z Thu Jan 1 00:00:00 1970 From: Rob Herring Subject: [PATCH] ASoC: Use of_node_name_eq for node name comparisons Date: Wed, 5 Dec 2018 13:50:49 -0600 Message-ID: <20181205195050.4759-33-robh@kernel.org> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: alsa-devel-bounces@alsa-project.org Sender: alsa-devel-bounces@alsa-project.org To: devicetree@vger.kernel.org, linux-kernel@vger.kernel.org Cc: alsa-devel@alsa-project.org, Timur Tabi , Xiubo Li , Takashi Iwai , Liam Girdwood , Nicolin Chen , Mark Brown , Fabio Estevam , linuxppc-dev@lists.ozlabs.org List-Id: devicetree@vger.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. For the FSL ASoC card, the full node names appear to be "ssi", "esai", and "sai", so there's not any reason to use strstr and of_node_name_eq can be used instead.
