[PATCH 02/29] rtc: ds1685: drop no_irq

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



No platforms are currently setting no_irq. Anyway, letting platform_get_irq
fail is fine as this means that there is no IRQ. In that case, clear
RTC_FEATURE_ALARM so the core knows there are no alarms.
