Put NULL test on the result of the previous call instead on one of its arguments. A simplified version of the semantic match that finds this problem is as follows (http://coccinelle.lip6.fr/): // <smpl> r@ expression *e1; expression *e2; identifier f; statement S1,S2; @@ e1 = f(...,e2,...); ( if (e1 == NULL || ...) S1 else S2 | *if (e2 == NULL || ...)
