commit 93b8809be5ba7d28218fd5561560c10cf058e998
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=93b8809be5ba7d28218fd5561560c10cf058e998



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

[ Upstream commit 708a49a6 ]

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: f52b041a ("libertas: Add spinlock to avoid race condition")
