One more thing, which I had intended to include in my earlier review

Please straighten out this convoluted logic. It should go like this:
hcd->phy = devm_of_phy_get(&pdev->dev, pdev->dev.of_node, NULL);
if (IS_ERR_OR_NULL(hcd->phy)) {
retval = PTR_ERR(hcd->phy);
if (retval == -EPROBE_DEFER || retval == -ENODEV)
return -EPROBE_DEFER;
dev_err(&pdev->dev, "failed to get the phy\n");
goto err_put_hcd;
}
