Message-ID: <558D5FF6.9030401@users.sourceforge.net> Date: Fri, 26 Jun 2015 16:21:42 +0200 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Andreas Dilger <adilger.kernel@...ger.ca>, Theodore Ts'o <tytso@....edu>, linux-ext4@...r.kernel.org CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH] fs-ext4 crypto: Delete an unnecessary check before the function call "key_put" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Fri, 26 Jun 2015 16:10:54 +0200 Subject: [PATCH] fs-ext4 crypto: Delete an unnecessary check before the function call "key_put" 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.
