[PATCH v3] alarmtimer: fix unexpected rtc interrupt when system resume from S3

e HPET RTC emulation fires an interrupt every 16ms(=1/2^DEFAULT_RTC_SHIFT) up to the point where the alarm time is reached. This program always hits this situation(https://lkml.org/lkml/2015/11/8/326), if system wake up earlier than alarm time. Cc: Thomas Gleixner Cc: John Stultz Signed-off-by: Zh

[PATCH v2] alarmtimer: fix unexpected rtc interrupt when system resume from S3

sleep over time. However, if the system wakeup early than RTC timeout, the RTC timer will not be cleared. And this will cause the hpet_rtc_interrupt come unexpectedly until the RTC timeout. To fix this problem, just adding alarmtimer_resume to cancel the RTC timer. Signed-off-by: Zhuo-hao Lee --- k
