[PATCH v2 4/4] libertas/cmdresp: don't call kfree_skb() under spin_lock_irqsave()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



It is not allowed to call kfree_skb() from hardware interrupt
context or with interrupts being disabled. So replace kfree_skb()
with dev_kfree_skb_irq() under spin_lock_irqsave(). Compile
tested only.
