I haven't had a lot of time to look over the code yet, but I don't think it's
quite there yet.

A few things I've noticed so far:
We now have functions vme_add_bus() and vme_remove_bus(). These seem to only
be called from vme_register_bridge() and vme_unregister_bridge(), these
functions being:
int vme_register_bridge(struct vme_bridge *bridge)
{
return vme_add_bus(bridge);
}
EXPORT_SYMBOL(vme_register_bridge);
void vme_unregister_bridge(struct vme_bridge *bridge)
{
vme_remove_bus(bridge);
}
EXPORT_SYMBOL(vme_unregister_bridge);
vme_add_bus() and vme_remove_bus() really don't need to be separate functions
as far as I can tell.
The comment starting on line 98 of vme.h no longer matches vme_dev.
The comment starting on line 1419 of vme.c states that iterating over the list
is safe WRT driver probing because the probe function calls vme_bridge_get().
This function no longer exists and I can't quickly see this lock being sought
in the new probing code, so is it still safe?
