From mboxrd@z Thu Jan 1 00:00:00 1970 From: Himangi Saraogi Subject: [PATCH] wireless: wlcore: Use devm_kzalloc Date: Thu, 7 Aug 2014 16:32:45 +0530 Message-ID: <20140807110244.GA10257@himangi-Dell> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: Julia Lawall To: "John W. Linville" , linux-wireless@vger.kernel.org, netdev@vger.kernel.org, linux-kernel@vger.kernel.org Return-path: Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org This patch introduces the use of devm_kzalloc and does away with the kfrees in the probe and remove functions. Also, a couple of labels and the initial assignment of the ret variable in the probe function are removed.
