| |
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 Raghavendra Chandra Ganiga Contact: +919594554858
