[PATCH] rtc framework handles periodic irqs
The RTC framework has an irq_set_freq() method that should be used to manage the periodic IRQ frequency, but the current ioctl logic doesn't know how to do that. This patch teaches it how. This means that drivers implementing irq_set_freq() will automatically support RTC_IRQP_{READ,SET} ioctls; that logic doesn't need duplication within the driver.
