From: Markus Elfring Date: Mon, 18 Jul 2016 07:00:00 +0000 (+0200) Subject: s390/pci: Delete an unnecessary check before the function call "pci_dev_put" X-Git-Tag: v4.8-rc1~167^2 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=64a40c84001e55001a4d80496b6b56e4d04e4360;p=linux.git s390/pci: Delete an unnecessary check before the function call "pci_dev_put" 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.
