Subject: [PATCH net-next 1/6] net: dsa: remove trans argument from mdb ops
Date:   Wed,  8 Nov 2017 12:19:12 -0500
Message-Id: <20171108171917.5965-2-vivien.didelot@savoirfairelinux.com>
In-Reply-To: <20171108171917.5965-1-vivien.didelot@savoirfairelinux.com>
References: <20171108171917.5965-1-vivien.didelot@savoirfairelinux.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The DSA switch MDB ops pass the switchdev_trans structure down to the
drivers, but no one is using them and they aren't supposed to anyway.

Remove the trans argument from MDB prepare and add operations.
