converting a driver from 2.4 kernel(comedi 0.7.68) into a 2.6 kernel(comedi 0.7.73)

Essentially i want to convert a driver that someone wrote under 2.4.27 with
comedi 7.68 ( i am told that it worked) into my current build 2.6.15 with
comedi 7.73. When I try to compile the comedi 0.7.70 that the driver was
sent with I get quite a few errors with
fops.c(class_simple_create/destroy/device_add/device_remove) , so i
decided to try
and update the driver to work in comedi 0.7.73 with the new kernel.  Here is
where the problem comes in, when i try to compile it ( i renamed it
skel.cfor simplicity, ) i get a quite a few errors, and tons of
warnings.  So far
i have just been looking for a different way to search the system for PCI
boards, since importing the old includes didn't work. the other thing that
is interesting is that within the entire comedi distribution,
pci_for_each_dev (for_each) only appears once, in my driver. anyways,
attached is the output of the make, any help or advice would be greatly
appreciated.

thanks,
-Christophe
