Merge tag 'pci-v6.16-fixes-4' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci fix from Bjorn Helgaas:

 - Create pwrctrl devices only when we need them, i.e., when
   CONFIG_PCI_PWRCTRL is enabled.

   This allows brcmstb to work around a pwrctrl regression by
   disabling CONFIG_PCI_PWRCTRL (Manivannan Sadhasivam)
