USB: r8a66597: clean up. remove unneeded null checks
td and dev can not be null. Also they are dereferenced in list_for_each_entry_safe and list_for_each before the check happens so we would have an oops if it were possible for them to be null. Found using the smatch static checker. Signed-off-by: Dan Carpenter <error27@gmail.com> Acked-by: Yoshihiro Shimoda <shimoda.yoshihiro@renesas.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
