staging: comedi: s626: remove boardinfo
This driver only supports one board type. Move the used board info out of the boardinfo struct and remove it. Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Cc: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
