Date: Fri, 21 Nov 2014 20:26:29 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: "David S. Miller" <davem@...emloft.net>, linux-ide@...r.kernel.org CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH 1/1] IDE: Deletion of an unnecessary check before the function call "module_put" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Fri, 21 Nov 2014 20:22:32 +0100 The module_put() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
