[PATCH v2 00/15] staging: comedi: 8255: tidy up the (*io) operations

[H Hartley Sweeten]

Now that the comedi_device has a 'mmio' and a 'iobase' member, this module
can updated to readb/writeb for memory mapped I/O or inb/outb for port I/O.
With this a lot of the code duplication can be removed in the drivers that
use the 8255 module.

 1) Modify a couple comedi drivers that use port I/O for the 8255 device so
    that the 'iobase' is used for the base address of the 8255 device.

 2) Add a comedi_device parameter to the (*io) callback. Tidy up the private
    (*io) callbacks to use this parameter.

 3) Modify the default (*io) callback to use the comedi_device 'iobase'. Remove
    the, now redundant, dev->iobase from the 'iobase' that is passed to
    subdev_8255_init() for all callers that use the default (*io) callback.

 4) Remove the unused and incomplete async command support from the 8255 module.

 5) Add a default (*io) callback to use the comedi_device 'mmio'. Remove
    the private (*io) callbacks that use readb/writeb to access the hardware.

v2: Fix the commit title for one of the patches (pointed out by Ian Abbott).
    Remove the async command support (suggested by Ian Abbott).
    Modify the 'mmio' support (suggested by Ian Abbott).
    Drop the conversion of amplc_dio200_common (requested by Ian Abbott).
