Subject: net: ns83820: use dev_kfree_skb_irq instead of kfree_skb
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0942170f32e1e9076f9a5f350250b8ec59ac04fa;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

net: ns83820: use dev_kfree_skb_irq instead of kfree_skb

It is not allowed to call kfree_skb() from hardware interrupt
context or with interrupts being disabled, spin_lock_irqsave()
make sure always in irq disable context. So the kfree_skb()
should be replaced with dev_kfree_skb_irq().

This is detected by Coccinelle semantic patch.
