Merge branch 'pci/deletion' into next
* pci/deletion:
PCI: Remove from bus_list and release resources in pci_release_dev()
PCI: Move pci_proc_attach_device() to pci_bus_add_device()
PCI: Use device_release_driver() in pci_stop_root_bus()
PCI: Move device_del() from pci_stop_dev() to pci_destroy_dev()
