The name gets a valid string by that point in time.

drivers/base/platform.c:257
int platform_device_add(struct platform_device *pdev)

        for (i = 0; i < pdev->num_resources; i++) {
                struct resource *p, *r = &pdev->resource[i];

                if (r->name == NULL)
                        r->name = pdev->dev.bus_id;
