From ff0387c3777f2438bad2088abe442c9f231b0be4 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Mon, 10 Nov 2014 21:02:17 -0700 Subject: PCI: Delete unnecessary NULL pointer checks The functions pci_dev_put(), pci_pme_wakeup_bus(), and put_device() return immediately if their argument is NULL. Thus the test before the call is not needed. Remove these unnecessary tests. This issue was detected by using the Coccinelle software.
