The kernel uses 32-bit signed value(time_t) for seconds since 1970-01-01:00:00:00, thus it will overflow at 2038-01-19 03:14:08 on 32-bit systems. We call this "2038 safety" issue. Currently, rtc_tm_to_time() deals with "unsigned long" which is 2038 unsafe on 32-bit systems. As part of addressing 2038 saftey for in-kernel uses, this patch creates no creates no functional change in existing users, renames rtc_tm_to_time() to rtc_tm_to_time_unsafe(), and changes all its calling users correspondingly. The safe version of rtc_tm_to_time() will be added in the following patch.
