Subject: [PATCH AUTOSEL 4.19 567/671] net: stmmac: dwmac-meson8b: Fix signedness bug in probe
Date: Thu, 16 Jan 2020 12:03:25 -0500
Message-ID: <20200116170509.12787-304-sashal@kernel.org> (raw)
In-Reply-To: <20200116170509.12787-1-sashal@kernel.org>
From: Dan Carpenter <dan.carpenter@oracle.com>
[ Upstream commit f10210517a2f37feea2edf85eb34c98977265c16 ]
The "dwmac->phy_mode" is an enum and in this context GCC treats it as
an unsigned int so the error handling is never triggered.
Fixes: 566e82516253 ("net: stmmac: add a glue driver for the Amlogic Meson 8b / GXBB DWMAC")
