This should be something like this

	struct device *dev = &spi->dev;
	struct fwnode_handle *fwnode = dev_fwnode(dev);

	if (is_acpi_device_node(fwnode)) {
		dev_set_name(dev, "spi-%s", acpi_dev_name(to_acpi_device_node(fwnode)));
		return;
	}

	if (is_software_node(fwnode)) {
		dev_set_name(dev, "spi-%s", fwnode_get_name(fwnode));
		return;
	}

i.o.w. we don't need to have two ways of checking fwnode type and you may get
rid of unneeded variable, and always use fwnode name for swnode.

Unneeded variable. See above.
