The name "nonpci_devs" for virtual devices is ambiguous as a physical device can also be non-PCI (ex: usb, sata, ...). A better name for this file is "vdev" as it only deals with virtual devices. This patch doesn't introduce any change except renaming. Signed-off-by: Olivier Matz <olivier.matz@6wind.com> Acked-by: Thomas Monjalon <thomas.monjalon@6wind.com>
