From mboxrd@z Thu Jan 1 00:00:00 1970 From: Lars-Peter Clausen Subject: [PATCH 4/5] ASoC: Remove 'reg_size' field from snd_soc_codec struct Date: Sat, 31 Aug 2013 20:31:14 +0200 Message-ID: <1377973875-2209-4-git-send-email-lars@metafoo.de> References: <1377973875-2209-1-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-180.synserver.de (smtp-out-180.synserver.de [212.40.185.180]) by alsa0.perex.cz (Postfix) with ESMTP id 813C62655A5 for ; Sat, 31 Aug 2013 20:29:50 +0200 (CEST) In-Reply-To: <1377973875-2209-1-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: alsa-devel@alsa-project.org, Lars-Peter Clausen List-Id: alsa-devel@alsa-project.org The reg_size field is calculated in snd_soc_register_codec() and then used exactly once in snd_soc_flat_cache_init(). Since it is calculated based on other fields from the codec struct just move the calculation to snd_soc_flat_cache_init() and remove the 'reg_size' field from the codec struct.
