The API looks to print debug messages. This print doesn't look required.

Does this do anything? Does this work just as well?
reset_gpio = devm_gpiod_get(chip->dev, "reset", GPIOD_OUT_LOW);
if (IS_ERR(reset_gpio))
return PTR_ERR(reset_gpio);
Note that there's no point to store the reset gpio in the structure if
it won't be used outside of probe. This should work fine? I used
GPIOD_OUT_LOW to indicate that the reset should be returned to this
function deasserted, i.e. taking the PMIC out of reset.
