    fuelgauge: max17042: fix i2c read issue which causes infinity loop. · c9b0fa31
    Przemyslaw Marczak authored
    Issues:
    - reading i2c data by passing u16 pointer causes errors in read data.
    - max17042 status register fields have not only Power On Reset meaning
      so using proper mask is required.
    
    Changes:
    - read i2c data to type u32 instead of u16 - avoids buffer overflow
    - compare FG status register using mask not just one bit value
    - add checking return value to functions fg read/write
    - add model lock and model check count
    - add debug msg
