serial_unlink_irq_chain() does not initialize iterator 'i', and that is
correct logically because it is always initialized, either in the
hlist_for_each or in the conditional immediately after (which fires if
hlist_for_each comes up empty-handed). GCC does not realize this
connection and emits a false warning. Annotate it with uninitialized_var().
