I guess this was fixed long ago by the following patch:

commit cf7a8c03db792894f436db5f3ffc44d947b9b068

    max17042_battery: Bugfix of incorrect voltage register value interpretation

    The calculation had error in getting voltage values from
    MAX17042 registers. The least bit denotes 78.125uV (625/8).
