I said clearly that I don't want this change to be made, because in many
cases the "= NULL" assignment in the driver is desirable to elide when it
isn't necessary because the value is already NULL.  Therefore the NULL
check in dev_kfree_skb_irq() is basically coming for free.

Yes there are other cases, but it really doesn't matter enough to justify
your change.

Thanks.
