From mboxrd@z Thu Jan 1 00:00:00 1970 From: Charles Keepax Subject: [PATCH 1/2] i2c: Remove unnecessary call to irq_find_mapping Date: Fri, 19 Oct 2018 09:59:57 +0100 Message-ID: <20181019085958.32694-1-ckeepax@opensource.cirrus.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-kernel-owner@vger.kernel.org To: wsa@the-dreams.de Cc: linux-i2c@vger.kernel.org, linux-kernel@vger.kernel.org, patches@opensource.cirrus.com List-Id: linux-i2c@vger.kernel.org irq_create_mapping calls irq_find_mapping internally and will use the found mapping if one exists, so there is no need to manually call this from i2c_smbus_host_notify_to_irq.
