So the alternative is that my device won't work on POWER9. Does that make sense?
What is the reason for this logic?
I'm not adding code that will be used by other drivers/users.
I'm just doing a special configuration to my device's H/W and I
condition it upon the PCI device ID of my parent PCI device.
What is the harm in that?
