[PATCH AUTOSEL 4.9 204/251] net: broadcom/bcmsysport: Fix signedness in bcm_sysport_probe()
From: Sasha Levin <sashal@kernel.org>
Date: 2020-01-16 18:01:30
Also in:
lkml, stable
Subsystem:
broadcom systemport ethernet driver, networking drivers, the rest · Maintainers:

[ Upstream commit 25a584955f020d6ec499c513923fb220f3112d2b ]
The "priv->phy_interface" variable is an enum and in this context GCC
will treat it as unsigned so the error handling will never be
triggered.
