The semantic match that finds this problem is: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,e; statement S1,S2; @@ *x = dev_get_platdata(...) ... when != x = e *if (x < 0) S1 else S2 // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Stefan Roese <sr@denx.de> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
