[rtc-linux] [PATCH v2 08/22] rtc: ds1305: stop using rtc deprecated functions

[Benjamin Gaignard <benjamin.gaignard@linaro.org>]

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.
