Thanks again.  This and related problems should be fixed by

 - 8a317a87 ([media] cx88: protect per-device driver list with device lock)
 - 1fe70e96 ([media] cx88: fix locking of sub-driver operations)
 - 1d6213ab ([media] cx88: hold device lock during sub-driver initialization)
 - 344d6c6b ([media] cx88: protect cx8802_devlist with a mutex)
 - 579b2b45 ([media] cx88: gracefully reject attempts to use unregistered
            cx88-blackbird driver)
 - f4bd4be8 ([media] cx88: don't use atomic_t for core->mpeg_users)

which are as of yesterday part of Linus's "master" branch fwiw.
