Russell, did you have a view on this series?

Following your suggestion I was able to use the generic modpost
infrastructure instead of reinventing stuff, and it seemes to work out
quite neatly.

Hopefully the only possibly-contraversial change change is the
movement of struct amba_id.

If it's already on your queue to look at then there's no need to rush.

Thanks
---Dave
