From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thomas Gleixner Subject: [patch 22/22] pinctrl/sunxi: Prepare sunxi_pinctrl_irq_handler for irq argument removal Date: Mon, 13 Jul 2015 20:48:07 -0000 Message-ID: <20150713072816.137686428@linutronix.de> References: <20150713072703.919712512@linutronix.de> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-15 Return-path: Received: from www.linutronix.de ([62.245.132.108]:56186 "EHLO Galois.linutronix.de" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1754325AbbGMUsP (ORCPT ); Mon, 13 Jul 2015 16:48:15 -0400 Content-Disposition: inline; filename=pinctrl-sunxi-prepare-sunxi_pinctrl_irq_handler-for-irq-argument-removal.patch Sender: linux-gpio-owner@vger.kernel.org List-Id: linux-gpio@vger.kernel.org To: LKML Cc: Linus Walleij , linux-gpio@vger.kernel.org, Jiang Liu , Julia Lawall The irq argument of most interrupt flow handlers is unused or merily used instead of a local variable. The handlers which need the irq argument can retrieve the irq number from the irq descriptor. Search and update was done with coccinelle and the invaluable help of Julia Lawall.
