staging: comedi: icp_multi: sample types are unsigned
Sample values in comedi are generally represented as unsigned values. Change the element type of the `ao_data[]` member of `struct icp_multi_private` from `short` to `unsigned short` for consistency. Also remove the `ai_data` and `di_data` members as they are not used. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
