From f78ed2204db9fc35b545d693865bddbe0149aa1f Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 7 May 2020 09:32:21 -0700 Subject: netpoll: accept NULL np argument in netpoll_send_skb() netpoll_send_skb() callers seem to leak skb if the np pointer is NULL. While this should not happen, we can make the code more robust. Signed-off-by: Eric Dumazet Signed-off-by: David S.
