Message-ID: <558AAEAF.7040606@users.sourceforge.net> Date: Wed, 24 Jun 2015 15:20:47 +0200 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: David Howells <dhowells@...hat.com>, James Morris <james.l.morris@...cle.com>, "Serge E. Hallyn" <serge@...lyn.com>, keyrings@...ux-nfs.org, linux-security-module@...r.kernel.org CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH] keys: Delete an unnecessary check before the function call "key_put" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Wed, 24 Jun 2015 15:16:35 +0200 The key_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.
