PCI: Add device flag helper functions
Add helper functions to hide direct device flag operations: void pci_set_dev_assigned(struct pci_dev *dev); void pci_clear_dev_assigned(struct pci_dev *dev); bool pci_is_dev_assigned(struct pci_dev *dev); Signed-off-by: Ethan Zhao <ethan.zhao@oracle.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
