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,...) S when != e = e1 when != e += e1 when != e -= e1 when != ++e when != --e when != e++ when != e-- when != &e kfree@p2(x); ... return ...; } @ok depends on unchanged exists@ position any r.p1; position r.p2; expression x; @@ ... when != true x@p1 == NULL kfree@p2(x); @depends on !ok && unchanged@ position r.p2; expression x; @@ *kfree@p2(x); // </smpl> Signed-off-by: Peter Senna Tschudin <peter.senna@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> |
