The kfree_skb() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.

You got the original patch and my ACK on this one or would you prefer me to resend it again?
this slipped through, but now it does no longer apply.
Applying: ieee802154-atusb: Delete an unnecessary check before the function call "kfree_skb"

Not good. I did another resend, this one applied, compiled and worked
fine for me. You will be in the to line.
