The point is to align with struct device life
The idea is to let vfio core manage the vfio_device life cycle instead
of duplicating the logic cross drivers. This is also a preparatory
step for adding struct device into vfio_device.
New pair of helpers together with a kref in vfio_device:
- vfio_alloc_device()
- vfio_put_device()
Drivers
