With commit e49656147359 {"rtlwifi: Use dev_kfree_skb_irq instead of

kfree_skb() was inside a spinlock. What was forgotten is that kfree_skb()
guards against a NULL value for the argument. Routine dev_kfree_skb_irq()
does not, and a test is needed to prevent kernel panics.
Fixes: commit e49656147359 {"rtlwifi: Use dev_kfree_skb_irq instead of kfree_skb")
This should be:

And this:
Cc: Stable <stable@xxxxxxxxxxxxxxx> # 4.9+
I can fix both of them.

Kalle,
This change should be sent to mainline during the 4.10 merge period,
or as soon as possible.
Ok, I'll queue this to 4.10. Most likely I'll send a pull request to
Dave later this week or so.
Thanks for the suggested changes, and for the quick action.
Larry
