You are right.

_GWS bit 0 reports the timer-expired status, including cases where the
timer expiration did not generate a pending alarm interrupt.
rtc_wkalrm::pending is not meant to report that state.

So mapping the _GWS expired bit to rtc_wkalrm::pending is incorrect. I
will drop this patch.

Thanks for the clarification.
