From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel Mack Subject: [PATCH] ALSA: ASoC: davinci-mcasp: clean ip davinci_hw_common_param() Date: Fri, 8 Mar 2013 14:19:38 +0100 Message-ID: <1362748778-11076-1-git-send-email-zonque@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: Received: from mail.zonque.de (svenfoo.org [82.94.215.22]) by alsa0.perex.cz (Postfix) with ESMTP id 99A1326171E for ; Fri, 8 Mar 2013 14:19:44 +0100 (CET) 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: alsa-devel@alsa-project.org Cc: broonie@opensource.wolfsonmicro.com, Michal Bachraty , Vaibhav Bedia , Daniel Mack List-Id: alsa-devel@alsa-project.org As pointed of by Vaibhav, commit 2952b27e2 ("ASoC: davinci-mcasp: Add support for multichannel playback") duplicated the logic of counting the active serializers. That can be avoided by shifting the code around a bit. Also, drop two unused defines introduced by the same commit.
