Miller" <davem@...emloft.net>, Sasha Levin <sashal@...nel.org> Subject: [PATCH 4.14 313/343] of: mdio: Fix a signedness bug in of_phy_get_and_connect() From: Dan Carpenter <dan.carpenter@...cle.com> [ Upstream commit d7eb651212fdbafa82d485d8e76095ac3b14c193 ] The "iface" variable is an enum and in this context GCC treats it as an unsigned int so the error handling is never triggered.
