From 776f07ee303a5e13970cbfaed767e28cbab4002f Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sat, 11 Aug 2018 21:19:19 -0700 Subject: brcmfmac: Use __skb_peek(). Instead of direct SKB list pointer accesses. In these situations, we absolutely know that the SKB queue in question is non-empty. Signed-off-by: David S.
