I think that checking the regmap_read/write return values is overkill
in this driver. These functions can't realistically fail, except if the i2c
bus is bad, i.e. h/w failure or intermittency. And that's an externality
which I believe we can ignore.

Maybe Thierry or Uwe have further insights here.
