commit 9db26d5855d0374d4652487bfb5aacf40821c469 upstream. When setting a normal alarm, user-space is responsible for using RTC_AIE_ON/RTC_AIE_OFF to control if alarm irq should be enabled. But when RTC_UIE_ON is used, interrupts must be enabled so that the requested irq events are generated. When RTC_UIE_OFF is used, alarm irq is disabled if there are no other alarms queued, so this commit brings symmetry to that.
