Subject[PATCH 3/3] PCI/ATS: Make pci_restore_pri_state(), pci_restore_pasid_state() private
From: Bjorn Helgaas <>

These interfaces:

void pci_restore_pri_state(struct pci_dev *pdev);
void pci_restore_pasid_state(struct pci_dev *pdev);

are only used in drivers/pci and do not need to be seen by the rest of the
kernel. Most them to drivers/pci/pci.h so they're private to the PCI
