The ADP1050 is used to monitor system voltages, currents and temperatures.
The ADP1050 and similar devices are used to monitor system voltages,
currents, power, and temperatures.

Through the PMBus interface, the ADP1050 targets isolated power supplies
and has four individual monitors for input/output voltage, input current
and temperature.

Also unrelated change. I would drop it (or add it in a different patch)

It can be const pmbus_driver_info *info

const pmbus_driver_info *info; returns an error similar to the one below. Will keep the original struct pmbus_driver_info *info;

Obviously a typo from me... const struct pmbus_driver_info *info and then no need for the cast

Yes, my bad... pmbus_do_probe() discards the const qualifier. Sorry for the noise.
