What do you think about the patch below? I would say it's pretty different from what I meant. You patch only delays the decision about the status of the pin while mine does really "average" the status of the pin. E.g. in my tosa PDA the headphones jack is a bit noisy. So the input layer shouldn't react to the noise. And with your patch each time the GPIO irq is generated the input layer will get input_sync. -- With best wishes Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
