staging: comedi: adv_pci_dio: absorb pci_dio_add_do()
This function initializes a digitial output subdevice. For aesthetics, absorb it into the (*auto_attach). Remove the improper initialization of the SDF_LSAMPL subdev_flag and len_chanlist. These are only used by subdevices that support async commands. Also remove the unnecessary initilaization of the subdevice 'state'.
