commit 21076167d7a67dc33ba671ce89b36f1be9ef2e51
Author: Thomas Schöpping <tschoepp@cit-ec.uni-bielefeld.de>
Date:   Mon Feb 4 17:36:52 2019 +0100

    Applied minor enhancements to all drivers.
    Please note: multiple functions should (and will) be moved from the .c sources to the header files as inline functions soon.
