The kernel complains that the PWM is not stopped ahead of being unexported. This may or may not be the case, but in any case, this helps avoid the kernel issue. Fixes beagleboard#154

If i remember correctly the reason I unexported the channels is because the pwm frequency can only be set once after export. Without the unexport the board would need to reboot to change PWM frequency. |

So finally, the channels have to be unexported right as per @StrawsonDesign ? Can someone provide clarity as to what is the status with this issue? |

The library should be fixed to export/unexport as needed. |
