The rtctest (tools/testing/selftests/timers/rtctest.c) found that reading ds3232 rtc device immediately return the value 0x20 (RTC_AF) without waiting alarm interrupt. This is because alarm_irq_enable() of ds3232 driver changes RTC_AF flag in rtc->irq_data. So calling ioctl with RTC_AIE_ON generates invalid value in rtc device. The lower-level driver should not touch rtc->irq_data directly. Signed-off-by:
