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
triggered.
Fixes: 533dd11a12f6 ("net: socionext: Add Synquacer NetSec driver")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
