#3 diocio48 device driver does not compile

[Mario Jorge R. de Sousa]

The diocio48 device driver does not compile on my
system (Debian Potato, Linux 2.2.17)

It seems we need to replace the put_fs_long() calls
with copy_to_user().

It would also be a good idea to check the version of
the linux kernel for which the device driver is being
compiled, and cop out if it is an un-suported version.

We might just as well add a comand line configuration
option to pass the base IO address of the cio48 card to
the device driver, instead of hardcoding it into the
code.

Support for the cio96 and cio192 cards could also be
included as a command line option, instead of
hardcoding it into the code too.
