2.5.4-pre1 (decoded) oops on boot in device_create_file

Must be my time of the year - first the kmem_cache_create one in
 2.5.3-pre[45], now this one (should happen about PCI allocation
 of one of the Xircom CardBus resources):

I had the same problem with 2.5.4-pre2. The patch below makes my
laptop able to boot again, but I don't know if the patch is correct.

That looks ok, since cardbus behaves internally much like PCI. 

I'll check if there's anything else that needs to happen.

Btw, thanks - I missed the original email in the sea of all the rest ;)

In the meantime I can confirm Peter's fix makes my laptop boot again :)
