[PATCH AUTOSEL 4.19 565/671] net: netsec: Fix signedness bug in netsec_probe()
From: Sasha Levin <sashal@kernel.org>
Date: 2020-01-16 18:39:42
Also in:
lkml, stable
Subsystem:
networking drivers, socionext (sni) netsec network driver, the rest · Maintainers:

From: Dan Carpenter <redacted>
[ Upstream commit bd55f8ddbc437c225391ca8f487e7ec10243c4cc ]
The "priv->phy_interface" variable is an enum and in this context GCC
will treat it as an unsigned int so the error handling is never
triggered.
