staging: comedi: usbdux: remove 'ao_continuous' from private data
This member of the private data can be determined from the cmd->stop_src. Do that instead. Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Reviewed-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
