I think you misunderstood. Buses are enumerated before this code is
reached and thus initdev_found() has already been called for all attached
block devices.

I would appreciate it if you could take a closer look at the locations where
initdev_found() and initdev_probe_done() are called and see if you still
think there is a problem.

I obviously need to do that.

However, one issue remains: If somebody wants to use your API for another bus, he needs to know at which point he can successfully use it, and after what point (or context) it cannot, even must not, be used anymore. This isn't documented --- or is it?

(By 'buses are enumerated before...' you surely mean only the buses for which you implemented this API usage already.)
