leaking_addresses: check if file name contains address
Sometimes files may be created by using output from printk. As the scan traverses the directory tree we should parse each path name and check if it is leaking an address. Add check for leaking address on each path name. Suggested-by: Tycho Andersen <tycho@tycho.ws> Acked-by: Tycho Andersen <tycho@tycho.ws> Signed-off-by: Tobin C. Harding <me@tobin.cc>
