staging: comedi: c6xdigio: tidy up C6X_encInput()
Rename the CamelCase function. For aesthetics, pass the comedi_device pointer instead of the dev->iobase as the first parameter. 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>
