instaspin-foc实验例程的问题

    在InstaSPIN-FOC的例程中，发现一个特点，就是声明为void 的函数，都会在函数体中加入一个return，这样有什么特别的意义么？

比如

void PWM_setPeriodLoad(PWM_Handle pwmHandle, const PWM_PeriodLoad_e periodLoad)
{
PWM_Obj *pwm = (PWM_Obj *)pwmHandle;


// clear the bits
pwm->TBCTL &= (~PWM_TBCTL_PRDLD_BITS);

// set the bits
pwm->TBCTL |= periodLoad;

return;
}
