The C file defines:

dvbpsi_descriptor_t * dvbpsi_GenStuffingDr(
                                        dvbpsi_stuffing_dr_t * p_decoded,
                                        int b_duplicate)
but the header file declares:
dvbpsi_descriptor_t * dvbpsi_GenStuffingDataDr(
                                        dvbpsi_stuffing_dr_t * p_decoded,
                                        int b_duplicate);

The patch fixes this (and also two wrong function names within 
comments).
