r600g: check NULL return from u_upload_alloc
Like done in si_state_draw.c::si_draw_vbo u_upload_alloc can fail, i.e. set output param *ptr to NULL, for 2 reasons: alloc fails or map fails. For both there is already a fprintf/stderr in radeon_create_bo and radeon_bo_do_map. In src/gallium/drivers/ it is a common usage to just avoid to crash by doing a silent check. But defer fprintf where the error comes from, libdrm calls. Signed-off-by: Julien Isorce <[email protected]> Reviewed-by: Marek Olšák <[email protected]>
