What error? Please don't interprete it - just cut'n'paste.

This is pretty fundamental, but non-standard stuff, especially
the return values. Probably the best source of info on this topic
is the Linux Device Drivers book 
(see  for an online copy).

If you live in Canberra, I think that there are some printed
copies at the Collins bookshop in Woden.

If you need help debugging, it normally helps to make the source
available somehow (a website if it is big, or attach it to an email).
