rtc_time_to_tm: fix signed/unsigned arithmetic
commit 945185a69daa457c4c5e46e47f4afad7dcea734f ("rtc: rtc_time_to_tm: use unsigned arithmetic") changed the some types in rtc_time_to_tm() to unsigned: void rtc_time_to_tm(unsigned long time, struct rtc_time *tm) { - register int days, month, year; + unsigned int days, month, year; This doesn't work for all cases, because days is checked for < 0 later on: if (days < 0) { year -= 1; days += 365 + LEAP_YEAR(year); } I think the correct fix would be to keep days signed and do an appropriate cast later on.
