STM32 RTC set_datetime returns a result but cannot fail

pub fn set_datetime(&mut self, t: DateTime) -> Result<(), RtcError> {

RTC::set_datetime method returns a Result<(), RtcError>, but implementation shows this method always returns Ok

This either lacks a check or error forwarding, as the docstring suggest:

Will return RtcError::InvalidDateTime if the datetime is not a valid range.

or maybe it could be simplified and not return any value.
