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. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
