> The for-loop iterates with a u8 loop counter i and compares this
> with the loop upper limit of num_parents that is an int type.
> There is a potential infinite loop if num_parents is larger than
> the u8 loop counter. Fix this by making the loop counter the same
> type as num_parents.  Also make num_parents an unsigned int to
> match the return type of the call to clk_hw_get_num_parents.
> 
> Addresses-Coverity: ("Infinite loop")
