Yang Yingliang cf48cb8deb mISDN: hfcmulti: don't call dev_kfree_skb/kfree_skb() under spin_lock_irqsave() ... [ Upstream commit 1232946cf5 ] It is not allowed to call kfree_skb() or consume_skb() from hardware interrupt context or with hardware interrupts being disabled. skb_queue_purge() is called under spin_lock_irqsave() in handle_dmsg() and hfcm_l1callback(), kfree_skb() is called in them, to fix this, use skb_queue_splice_init() to move the dch->squeue to a free queue, also enqueue the tx_skb and rx_skb, at last calling __skb_queue_purge() to free the SKBs afer unlock.
