Since we are not returning error here, so changed to dev_warn. If the regulators are required, then any failure to operate them should be an error, hence dev_err() seems correct. As to why the code doesn't actually return an error? I'm not sure. Perhaps that should be fixed with a separate patch, although I don't recall exactly where in the code the above excerpt is; if it's in remove(), then continuing on without returning an error would be appropriate. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
