Silva" Subject: [PATCH] i40e/virtchnl: fix application of sizeof to pointer Date: Wed, 18 Oct 2017 15:34:25 -0500 Message-ID: <20171018203425.GA983@embeddedor.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: intel-wired-lan@lists.osuosl.org, netdev@vger.kernel.org, linux-kernel@vger.kernel.org, "Gustavo A. R. Silva" To: Jeff Kirsher Return-path: Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org sizeof when applied to a pointer typed expression gives the size of the pointer. The proper fix in this particular case is to code sizeof(*vfres) instead of sizeof(vfres). This issue was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R.
