Overall, this is the right way to go, using a vme_dev.

BUT, you should never have a static list of devices, these should be
pointers, not actual structures here, otherwise your reference counting
just got all messed up and is wrong.

And yes, I know you didn't create the code this way, but it needs to be
fixed _before_ you make this kind of a change.
