staging: comedi: comedi_parport: use comedi_buf_write_samples()

Use comedi_buf_write_samples() to add the sample to the async buffer. The async events COMEDI_CB_BLOCK and COMEDI_CB_EOS will be detected and set by the core. Remove the unnecessary events in the driver. Signed-off-by: H Hartley Sweeten <[email protected]> Reviewed-by: Ian Abbott <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
