    sched/cputime: Refactor the cputime_adjust() code · 72298e5c
    Gustavo A. R. Silva authored
    Address a Coverity false positive, which is caused by overly
    convoluted code:
    
    Value assigned to variable 'utime' at line 619:utime = rtime;
    is overwritten at line 642:utime = rtime - stime; before it
    can be used. This makes such variable assignment useless.
    
    Remove this variable assignment and refactor the code related.
