Date: Mon, 02 Feb 2015 22:22:32 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Bartlomiej Zolnierkiewicz <b.zolnierkie@...sung.com>, Tejun Heo <tj@...nel.org>, 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] ata: Delete unnecessary checks before the function call "pci_dev_put" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Mon, 2 Feb 2015 22:08:29 +0100 The pci_dev_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.
