x86, mce, AMD: Fix leaving freed data in a list
commit d9a5ac9ef306eb5cc874f285185a15c303c50009 upstream. b may be added to a list, but is not removed before being freed in the case of an error. This is done in the corresponding deallocation function, so the code here has been changed to follow that. The sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression E,E1,E2; identifier l; @@ *list_add(&E->l,E1); ... when != E1 when != list_del(&E->l) when != list_del_init(&E->l) when != E = E2 *kfree(E);// </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Borislav Petkov <borislav.petkov@amd.com> Cc: Robert Richter <robert.richter@amd.com> Cc: Yinghai Lu <yinghai@kernel.org> Cc: Andreas Herrmann <andreas.herrmann3@amd.com> Link: http://lkml.kernel.org/r/1305294731-12127-1-git-send-email-julia@diku.dk Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
