Please avoid these unnecessary whitespace changes, they just make the
patch bigger.

Is this struct going to be used by functions outside devinst.c?  If
not then this should be moved into that file.

Also please include a test with your patch and, in this case, I think
it makes sense to include the appropiate Destroy function too, that
way it's easy to check that you haven't introduced a memory leak.

Thanks,
Huw.
