Merge branch 'pci/misc'

- Check pcie_find_root_port() return in x86 fixups to avoid NULL pointer
  dereferences (Samasth Norway Ananda)

- Make pci_bus_type constant (Kunwu Chan)

- Remove unused declarations of __pci_pme_wakeup() and pci_vpd_release()
  (Yue Haibing)

- Remove any leftover .*.cmd files with make clean (zhang jiao)

* pci/misc:
  PCI: Fix typos
  PCI/VPD: Remove pci_vpd_release() unused declarations
  PCI/PM: Remove __pci_pme_wakeup() unused declarations
  PCI: Make pci_bus_type constant
  x86/PCI: Check pcie_find_root_port() return for NULL
