Missing documentation for this compatible property.  Also, it appears
to be rather on the generic side.

.probe needs to be put into the __devinit section.

Similarly, at the same time the remove hook should be changed to
__devexit and __devexit_p() at the same time.

Looks like ".owner = THIS_MODULE," is missing too.
