Subject: [PATCH net] net: netsec: Fix signedness bug in netsec_probe()
Date: Wed, 25 Sep 2019 13:56:38 +0300	[thread overview]
Message-ID: <20190925105638.GE3264@mwanda> (raw)

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

Fixes: 533dd11a12f6 ("net: socionext: Add Synquacer NetSec driver")
