It seems to me the problem is here:
drivers/rtc/rtc-m48t59.c
static int m48t59_rtc_read_time(struct device *dev, struct rtc_time *tm)
/* tm->tm_year is 108 here */
val = M48T59_READ(M48T59_WDAY);
if ((pdata->type == M48T59RTC_TYPE_M48T59) &&
(val & M48T59_WDAY_CEB) && (val & M48T59_WDAY_CB)) {
dev_dbg(dev, "Century bit is enabled\n");
tm->tm_year += 100; /* one century */
}
/* tm->tm_year is 208 here */
Finally year becomes 2108.
It should not enter this condition.
Is it obvously how to rewrite the condition or is the problem in another place?
