From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jyri Sarha Subject: [PATCH v3] ASoC: soc-core: Fix sparse warning in be32_to_cpup() call Date: Thu, 17 Sep 2015 13:13:38 +0300 Message-ID: <1442484818-30983-1-git-send-email-jsarha@ti.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: Received: from arroyo.ext.ti.com (arroyo.ext.ti.com [192.94.94.40]) by alsa0.perex.cz (Postfix) with ESMTP id 40DE4265289 for ; Thu, 17 Sep 2015 12:13:43 +0200 (CEST) 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: linux-omap@vger.kernel.org, alsa-devel@alsa-project.org Cc: peter.ujfalusi@ti.com, liam.r.girdwood@linux.intel.com, broonie@kernel.org, Jyri Sarha List-Id: alsa-devel@alsa-project.org Store return value of of_get_property() to a pointer of __be32 type as device tree has big endian type. This fixes a sparse warning couple of lines later when be32_to_cpup() is used to convert from big endian to cpu endian. The whole conversion is not really necessary, as we are only checking if the value is zero or not, but I wanted to add it to remind in the future that the data has to be converted before use. Compiler should optimize the unnecessary operations away. Signed-off-by: Jyri Sarha --- Damn, I wrote description ready but forgot to produce the patch again.
