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.
