This is out of topic here.  You should have asked that question in the LKML
mailinglist (http://www.kernel.org/pub/linux/docs/lkml/).

Anyway, here's your answer.  You won't like it.

You wrote your driver for a dead branch that has been on deep maintenance
mode for many years now (Linux 2.4.x).  You will have to port (more like
rewrite) your kernel driver for the recent 2.6 kernels, the two code bases
have diverged a _lot_.

I suggest you look for one of the embedded Linux driver developer
communities and ask about how best to proceed.  But before you do, at least
read these quick presentations:




Pay attention of what they have to say about "embedded devices with
out-of-tree, closed source drivers".  Even if your company doesn't deal with
an embedded device, it is equally valid for any out-of-tree kernel driver.
