Stray change.

 	mem = platform_get_resource(pdev, IORESOURCE_MEM, 0);
 	irq = platform_get_irq(pdev, 0);
 	if (!mem || irq < 0)
 		return -ENXIO;

+	if (!base_addr) {
+		dev_err(&pdev->dev, "Failed to ioremap ethernet registers\n");
+		return -EIO;
+	}

Why not switching to devm_platform_ioremap_resource()?

...

+	if (of_property_read_u32(np, "reg", &phy_id)) {
+		dev_err(&pdev->dev, "Failed to locate \"phy_id\"\n");
+		return -ENOENT;

		return dev_err_probe(...); ?

+	}
