PCI: Make pci_bus_add_device() void
pci_bus_add_device() always returns 0, so there's no point in returning anything at all. Make it a void function and remove the tests of the return value from the callers. [bhelgaas: changelog, remove unused "err" from i82875p_setup_overfl_dev()] Signed-off-by: Yijing Wang <wangyijing@huawei.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
