If anyone has any objections, please let me know. ------------------ From: Ian Abbott commit f6b316bcd8c421acd6fa5a6e18b4c846ecb9d965 upstream. Use comedi_dio_update_state() to handle the boilerplate code to update the subdevice s->state. Also, fix a bug where the state of the channels is returned in data[0]. The comedi core expects it to be returned in data[1].
