Kfree can cope with a null argument, so drop null tests. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression ptr; @@ - if (ptr != NULL) kfree(ptr); // </smpl> This patch additionally simplifies one case where the free, and thus the jump to the end of the function, is not needed.
