We initialize the data->mutex in gpiod_export() but lack the corresponding mutex_destroy() in gpiod_unexport() causing a resource leak with mutex debugging enabled. Add the call right before kfreeing the GPIO data.
No, there's no resource leak and it's perfectly fine not to call mutex_destroy().
You can't just make shit up and then pretend to fix it...
