Populate the file descriptor for the device On a GPIO chip, there could be many gpio lines and for each line, there would be a corresponding input device event file. To know the assertion state of a GPIO line, a descriptor is needed. This descriptor will later be plugged into sd_event so that the GPIO state changes can be caught and handled.
