Subject: [PATCH net] net: netsec: Fix signedness bug in netsec_probe()

From: Dan Carpenter <[email-masked]>
Date: Wed, 25 Sep 2019 13:56:38 +0300

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.

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