This patch removes overhead condition check in blobtracker driver (similar to that removed from blobtodio) which limits usability of published dio data (before patch: no publish when no blobs, while it should remark no blobs by setting dio bit to zero: no blobs, nothing can be found).

The changes have been made in SVN trunk.
Thank you for your contribution.
