Ok, we've established that you and I know it's fine. Great :-)
I was more concerned with the larger question that contexts like this,
assignment of __init function pointers to dynamic data structure
members, is not checked.
The checker has no way to make sure that pbm->scan_bus() is only
made in __init contexts, even though we can plainly see that is
the case here.
What would be really clever would be a way to mark datastructure
members as "this is a pointer to an __init function".
