rtc_get_memory() and rtc_set_memory() helpers only work with
TYPE_MC146818_RTC devices. 'memory' in their name refer to
the CMOS region. Rename them as mc146818rtc_get_cmos_data()
and mc146818rtc_set_cmos_data() to be explicit about what
they are doing.
Mechanical change doing:
$ sed -i -e 's/rtc_set_memory/mc146818rtc_set_cmos_data/g' \
$(git grep -wl rtc_set_memory)
$ sed -i -e 's/rtc_get_memory/mc146818rtc_get_cmos_data/g' \
$(git grep -wl rtc_get_memory)
