From: Julia Lawall <julia@xxxxxxx> The function map_iovm_area is static and is only called from one place, at which the "new" argument cannot be NULL. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; expression E,E1; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E=E1 when != i if (E == NULL||...)
