> A for-loop is using a u8 loop counter that is being compared to a u32
> cmp_dcbcfg->numapp to check for the end of the loop. If cmp_dcbcfg-
> >numapp is larger than 255 then the counter j will wrap around to zero and
> hence an infinite loop occurs. Fix this by making counter j the same type as
> cmp_dcbcfg->numapp.
