Remove useless kfree() and clean up code related to the removal. The semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ position p1,p2; expression x; @@ if (x@p1 == NULL) { ... kfree@p2(x); ... return ...; } @unchanged exists@ position r.p1,r.p2; expression e <= r.x,x,e1; iterator I; statement S; @@ if (x@p1 == NULL) { ... when != I(x,...)
