* drivers/rtc/interface.c: fix infinite loop in initializing the alarmAles Novak2017-04-131-2/+12
| | | | | | | | | | | | | | | | In __rtc_read_alarm(), if the alarm time retrieved by rtc_read_alarm_internal() from the device contains invalid values (e.g. month=2,mday=31) and the year not set (=-1), the initialization will loop infinitely because the year-fixing loop expects the time being invalid due to leap year. Fix reduces the loop to the leap years and adds final validity check.

* drivers/rtc/interface.c: check the error after __rtc_read_time()Hyogi Gim2017-04-131-0/+2
| | | | | | | | | | | | | In __rtc_set_alarm(), the error after __rtc_read_time() is not checked. If rtc device fail to read time, we cannot guarantee the following process. Add the verification code for returned __rtc_read_time() error.
