The patch titled Subject: drivers/rtc/interface.c: check the validation of rtc_time in __rtc_read_time has been removed from the -mm tree. Its filename was drivers-rtc-interfacec-check-the-validation-of-rtc_time-in-__rtc_read_time.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Hyogi Gim <ciogenis@xxxxxxxxx> Subject: drivers/rtc/interface.c: check the validation of rtc_time in __rtc_read_time Some rtc devices always return '0' when rtc_class_ops.read_time is called. So if rtc_time isn't verified in callback, rtc interface cannot know whether rtc_time is valid. Check rtc_time by using 'rtc_valid_tm' in '__rtc_read_time'. And add the message for debugging.
