[Mesa-dev] [PATCH 1/1] mesa/st: draw_vbo: initialize restart_index too

[Gert Wollny]

From: Gert Wollny <gert.wollny at collabora.com>

restart_index is later always used in a comparison, so it should be
initialized properly.

Fixes valgrind warning:
 Conditional jump or move depends on uninitialised value(s)
