From mboxrd@z Thu Jan 1 00:00:00 1970 From: Florian Fainelli Subject: [PATCH net-next v2 1/3] net: dsa: Do not check for NULL dst in tag parsers Date: Sat, 8 Apr 2017 08:55:21 -0700 Message-ID: <20170408155523.20447-2-f.fainelli@gmail.com> References: <20170408155523.20447-1-f.fainelli@gmail.com> Cc: davem@davemloft.net, andrew@lunn.ch, vivien.didelot@savoirfairelinux.com, sean.wang@mediatek.com, Florian Fainelli To: netdev@vger.kernel.org Return-path: Received: from mail-it0-f66.google.com ([209.85.214.66]:32833 "EHLO mail-it0-f66.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751730AbdDHPza (ORCPT ); Sat, 8 Apr 2017 11:55:30 -0400 Received: by mail-it0-f66.google.com with SMTP id w11so1620662itb.0 for ; Sat, 08 Apr 2017 08:55:30 -0700 (PDT) In-Reply-To: <20170408155523.20447-1-f.fainelli@gmail.com> Sender: netdev-owner@vger.kernel.org List-ID: dsa_switch_rcv() already tests for dst == NULL, so there is no need to duplicate the same check within the tag receive functions.
