Subject: [PATCH V2 1/1] net: ethernet: stmmac: drop unused variable in stm32mp1_set_mode()
Date:   Mon, 4 Nov 2019 11:51:00 +0100
Message-ID: <20191104105100.4288-1-christophe.roullier@st.com>

Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Building with W=1 (cf.scripts/Makefile.extrawarn) outputs:
warning: variable ‘ret’ set but not used [-Wunused-but-set-variable]

Drop the unused 'ret' variable.
