Subject: [PATCH 03/11] vfio-pci: rename vfio_pci_device to vfio_pci_core_device
This is a preparation patch for separating the vfio_pci driver to a
subsystem driver and a generic pci driver. This patch doesn't change
any logic. The new vfio_pci_core_device structure will be the main
structure of the core driver and later on vfio_pci_device structure will
be the main structure of the generic vfio_pci driver.
