Subject: [PATCH net v2 0/3] mISDN: don't call dev_kfree_skb/kfree_skb() under spin_lock_irqsave()

It is not allowed to call kfree_skb() or consume_skb() from hardware
interrupt context or with hardware interrupts being disabled. This
pachset try to avoid calling dev_kfree_skb/kfree_skb()() under
spin_lock_irqsave().

v1 -> v2:
  Use skb_queue_splice_init() to move the 'squeue' to a free queue, then purge it.

Yang Yingliang (3):
  mISDN: hfcsusb: don't call dev_kfree_skb/kfree_skb() under
    spin_lock_irqsave()
  mISDN: hfcpci: don't call dev_kfree_skb/kfree_skb() under
    spin_lock_irqsave()
  mISDN: hfcmulti: don't call dev_kfree_skb/kfree_skb() under
    spin_lock_irqsave()
