Well, here you have missed the point of direction: ... + err = gpio_request_one(pdata->gpio_pendown, GPIOF_DIR_IN, + "ads7846_pendown"); ... - err = gpio_request_one(pdata->gpio_pendown, GPIOF_DIR_IN, - "ads7846_pendown"); ... It does not deal with direction, but only with request - free balance. The gpio direction is fixed by your patch. -- Regards, Igor. -- 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
