Thanks a lot for the analyse and for fixing this. May I ask however to
follow a more common pattern for error checking that is:

       error = dev_set_name(...);
       if (error)
                goto...

This way it is closer to the usual error handling and also aligned with
the rest of the file.

Otherwise LGTM.

Thanks,
Miquèl
