commit 647230e71e1c306810996966721ad581899d5b2c
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=647230e71e1c306810996966721ad581899d5b2c



--------------------------------

[ Upstream commit 3968e81b ]

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.

Fixes: a3128fee ("libertas: use irqsave() in USB's complete callback")
