I don't think there's going to be any v6, as there's nothing else to do on
this series.

Mark, if you want to fix this up before applying, that should then be, exactly

		rdev = devm_regulator_register(&pdev->dev, vrdesc, &config);
		if (IS_ERR(rdev))
			dev_err_probe(&pdev->dev, PTR_ERR(rdev),
				      "failed to register %s\n", vrdesc->name);

Otherwise, nevermind I guess..?
