Subject: staging: comedi: contec_pci_dio: define register map for board
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=86d466b86e0c04b2f0f6ae41f0de75082865912d;p=linux-beck.git

staging: comedi: contec_pci_dio: define register map for board

Only one board type is supported by this driver. Instead of
passing the register offsets for the digital in/out ports in
the boardinfo, define the register map and use that to access
the ports.
