wifi: ipw2x00: don't call dev_kfree_skb() under spin_lock_irqsave()
stable inclusion from stable-v5.10.173 commit 841ae9b924f4e7ff3bfa887fafb113a6665d01ff category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8BFR3 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=841ae9b924f4e7ff3bfa887fafb113a6665d01ff -------------------------------- [ Upstream commit 45fc6d74 ] It is not allowed to call kfree_skb() or consume_skb() from hardware interrupt context or with hardware interrupts being disabled. It should use dev_kfree_skb_irq() or dev_consume_skb_irq() instead. The difference between them is free reason, dev_kfree_skb_irq() means the SKB is dropped in error and dev_consume_skb_irq() means the SKB is consumed in normal. In this case, dev_kfree_skb() is called to free and drop the SKB when it's reset, so replace it with dev_kfree_skb_irq(). Compile tested only. Fixes: 43f66a6c ("Add ipw2200 wireless driver.")
