Subject: [PATCH] net/amd: Fix unused assignment in au1000_probe()
Date:   Tue, 19 May 2020 19:16:50 +0800
Message-Id: <20200519111650.17008-1-tangbin@cmss.chinamobile.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Delete unused initialized value of 'err', because it will
be assigned by the function mdiobus_register(). And the
variable 'err = -ENODEV' is duplicate, so remove redundant
one.
