Subjectquery regarding not returning error if request_irq fails after rtc registration
in ds1343 driver after the rtc is registered using devm_rtc_device_register
i am requesting irq using devm_request_threaded_irq, in case this request
fails instead of the driver bailing out it just uses dev_err to show the
error and the driver probe returns zero

my question is that the set_alarm and alarm_irq_enable is still active,
so should i use some flag in the global private variable of the driver
so that if the request irq fails, then using this flag the set_alarm
and alarm_irq_enable can return error since there is no irq handler
for the rtc interrupt
or is there any other solution
or let the set_alarm and alarm_irq_enable routine be as it is and will
not harm

Thanks and Regards
