Clean up compiler warning in ts2phc_pps_sink.c. v2 - reformat commit message Gcc (and presumably other compilers) emits a warning about the declaration of 'sink' shadowing a previous local in ts2phc_pps_sink.c. This warning is completely benign but makes it more difficult to recognize warnings that might be consequential. This patch reuses the previous declaration of sink which is also a pointer to a struct ts2phc_pps_sink. Signed-off-by: Michael Galassi <michael@galassi.us>
