Subject: [PATCH net-next v2 2/3] net: phy: xgmiitorgmii: Use correct mdio bus
Date:   Tue, 26 Jun 2018 12:50:49 -0500
Message-Id: <20180626175050.71165-2-brandon.maier@rockwellcollins.com>
In-Reply-To: <20180626175050.71165-1-brandon.maier@rockwellcollins.com>
References: <20180626175050.71165-1-brandon.maier@rockwellcollins.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The xgmiitorgmii is using the mii_bus of the device it's attached to,
instead of the bus it was given during probe.
