    Subjectorinoco driver causes *lots* of lockdep spew
    Wow. Nearly 400 lines of debug spew, from a simple 'ifup eth1'.

    ADDRCONF(NETDEV_UP): eth1: link is not ready
    eth1: New link status: Disconnected (0002)

    ======================================================
    [ INFO: hard-safe -> hard-unsafe lock order detected ]
    ------------------------------------------------------
    events/0/5 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
    (af_callback_keys + sk->sk_family){-.--}, at: [<ffffffff802136b1>] sock_def_readable+0x19/0x6f

    and this task is already holding:
    (&priv->lock){++..}, at: [<ffffffff8824f70e>] orinoco_send_wevents+0x28/0x8b [orinoco]
    which would create a new lock dependency:
    (&priv->lock){++..} -> (af_callback_keys + sk->sk_family){-.--}

    but this new dependency connects a hard-irq-safe lock:
    (&priv->lock){++..}
    ... which became hard-irq-safe at:
    [<ffffffff802a8e62>] lock_acquire+0x4a/0x69
    [<ffffffff80267ba2>] _spin_lock_irqsave+0x2b/0x3c

    [<ffffffff8026fca8>] do_IRQ+0xf7/0x107
    [<ffffffff802609c4>] common_interrupt+0x64/0x65

    to a hard-irq-unsafe lock:
    (af_callback_keys + sk->sk_family){-.--}
    ... which became hard-irq-unsafe at:
    ... [<ffffffff802a8e62>] lock_acquire+0x4a/0x69
