From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sergei Shtylyov Subject: [PATCH] of_mdio: kill useless variable in of_mdiobus_register() Date: Sun, 28 Feb 2016 21:56:34 +0300 Message-ID: <76681790.JernGlLJsj@wasted.cogentembedded.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7Bit Return-path: Sender: netdev-owner@vger.kernel.org To: grant.likely@linaro.org, robh+dt@kernel.org, devicetree@vger.kernel.org, f.fainelli@gmail.com, netdev@vger.kernel.org, frowand.list@gmail.com List-Id: devicetree@vger.kernel.org of_mdiobus_register() declares the 'paddr' variable to hold the result of the of_get_property() but only uses it once after that while the function can be called directly from the *if* statement. Remove that variable and switch to calling of_find_property() instead since we don't care about the "reg" property's value anyway...
