Subject[PATCH 20/51] rtc: ds1374: stop using rtc deprecated functions
Message-ID<tUo70-6Xh-23@gated-at.bofh.it>
rtc_time_to_tm() and rtc_tm_to_time() are deprecated because they
rely on 32bits variables and that will make rtc break in y2038/2016.
Stop using those two functions to safer 64bits ones.
