[PATCH 22/35] staging: comedi: cb_pcimdda: remove the DIO_METHODS

From: H Hartley Sweeten
Date: Thu Aug 16 2012 - 22:50:21 EST


The digital i/o on this card is handled by an 8255 compatible
device. There are not other options. Remove the DIO_METHODS
enum as well as the dio_method variable in the boardinfo and
the code dealing with it.
