In ssb_calc_clock_rate(), there is a potential issue where the value of m1 could be zero due to initialization using clkfactor_f6_resolv(). This situation raised concerns about the possibility of a division by zero error. We fixed it by following the suggestions provided by Larry Finger <Larry.Finger@xxxxxxxxxxxx> and Michael Büsch <m@xxxxxxx>. The fix involves returning a value of 1 instead of 0 in clkfactor_f6_resolv(). This modification ensures the proper functioning of the code and eliminates the risk of division by zero errors.
