Message-ID: <558D70C2.4080406@users.sourceforge.net> Date: Fri, 26 Jun 2015 17:33:22 +0200 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Changman Lee <cm224.lee@...sung.com>, Jaegeuk Kim <jaegeuk@...nel.org>, linux-f2fs-devel@...ts.sourceforge.net CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH] f2fs crypto: Delete an unnecessary check before the function call "key_put" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Fri, 26 Jun 2015 17:28:55 +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.
