staging: comedi: 8255: sample types are unsigned
Sample values in comedi are generally represented as unsigned values. `subdev_8255_interrupt()` calls `comedi_buf_put()` with a `short` data value merely because that's what was previously expected. Since it now expects an `unsigned short`, change it here for consistency. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
