In this case it should be &pdev->dev rather than pdev->dev.parent. The dev parameter is used to call devm_kzalloc in of_get_regulator_init_data(), which means this fixes a memory leak because the memory is allocated every time probe() is called, thus it should be freed when this driver is unloaded.
