From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lars-Peter Clausen Subject: [PATCH 08/19] ASoC: kirkwood: Don't set unused struct snd_pcm_hardware fields Date: Fri, 20 Dec 2013 14:20:14 +0100 Message-ID: <1387545625-19240-8-git-send-email-lars@metafoo.de> References: <1387545625-19240-1-git-send-email-lars@metafoo.de> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: Received: from smtp-out-044.synserver.de (smtp-out-122.synserver.de [212.40.185.122]) by alsa0.perex.cz (Postfix) with ESMTP id 648EF26566F for ; Fri, 20 Dec 2013 15:19:39 +0100 (CET) In-Reply-To: <1387545625-19240-1-git-send-email-lars@metafoo.de> 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: Mark Brown , Liam Girdwood Cc: Jean-Francois Moine , alsa-devel@alsa-project.org, Lars-Peter Clausen List-Id: alsa-devel@alsa-project.org The ASoC core assumes that the PCM component of the ASoC card transparently moves data around and does not impose any restrictions on the memory layout or the transfer speed. It ignores all fields from the snd_pcm_hardware struct for the PCM driver that are related to this. Setting these fields in the PCM driver might suggest otherwise though, so rather not set them.
