Use IS_ERR() instead of IS_ERR_OR_NULL() because devm_of_phy_get_by_index()
never return NULL value;
But still need ignore the error of -ENODEV, for more information, please

Perhaps the patch Subject is a little misleading as this is more of a
clean up than a fix (as there's no bug here).
But apart from that this looks good to me.
