Subject: i915g: Call draw_set_mapped_vertex_buffer from draw_vbo
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6ef37f71b0a0460808bb68a9102c15f313492c9f;p=mesa.git

i915g: Call draw_set_mapped_vertex_buffer from draw_vbo

This regressed with the draw rework. Fixes glest and vdrift crash.
