Clemens Gruber 6ef213d621 pwm: pca9685: Fix period change with same duty cycle ... commit 8d254a340efb12b40c4c1ff25a48a4f48f7bbd6b upstream. When first implementing support for changing the output frequency, an optimization was added to continue the PWM after changing the prescaler without having to reprogram the ON and OFF registers for the duty cycle, in case the duty cycle stayed the same. This was flawed, because we compared the absolute value of the duty cycle in nanoseconds instead of the ratio to the period. Fix the problem by removing the shortcut.
