From: Julia Lawall <ju...@diku.dk> list_for_each_entry binds its first argument to a non-null value, and thus any null test on the value of that argument is superfluous.
The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ iterator I; expression x,E,E1,E2; statement S,S1,S2; @@ I(x,...) { <... - if (x != NULL || ...)
