`.driver.name =  KBUILD_MODNAME` also seems very common, should we put
that in the macro as well?

This is a bit different thing. Every driver is expected to set owner to
itself (THIS_MODULE), but is every driver name KBUILD_MODNAME?

Nope, IIUC we have 2 exceptions:
- drivers/firmware/arm_scmi/virtio.c
- arch/um/drivers/virt-pci.c

Remember that this overrides whatever driver actually put there.

They can call __register_virtio_driver() where we can add the `name`
parameter. That said, I don't have a strong opinion, we can leave it
as it is.

Thanks,
Stefano
