We intend to derive the platform driver into specialized ones, featuring
reset modality. In order to avoid duplication, let's export the functions
that can be reused in all vfio_platform drivers:
- get_platform_resource
- get_platform_irq
- vfio_platform_probe
- vfio_platform_remove
Practically, only the vfio_platform_probe method should need to be
overridden.
