From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The check for secs being less than zero is redundant for two reasons.
Firstly, secs is unsigned so the check is always going to be false.
Secondly, if secs was signed the proceeding calculation of secs is
never going to be negative. Hence we can remove this redundant check
and day and secs re-adjustment.
Detected by static analysis with smatch:
arcmsr_set_iop_datetime() warn: unsigned 'secs' is never less than zero.
