This driver has a number of y2038/y2106 issues. This patch resolves them by: - Repalce get_seconds() with ktime_get_real_seconds() - Replace rtc_time_to_tm() with rtc_time64_to_tm() Also add test_rtc_set_mmss64() for testing rtc_class_ops's set_mmss64(), which can be activated by "test_mmss64" module parameter.
