drivers/base/core.c: Remove two unused variables and two useless calls to kfree
old_class_name, and new_class_name are never used. This patch remove the declaration and calls to kfree. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r1 forall@ type T; identifier i; @@ * T *i = NULL; ... when != i * kfree(i); // </smpl> Signed-off-by: Peter Senna Tschudin <peter.senna@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
