Subject: [PATCH net] net: hisilicon: Fix signedness bug in hix5hd2_dev_probe()
Date: Wed, 25 Sep 2019 13:55:32 +0300 [thread overview]
Message-ID: <20190925105532.GC3264@mwanda> (raw)
The "priv->phy_mode" variable is an enum and in this context GCC will
treat it as unsigned to the error handling will never trigger.
Fixes: 57c5bc9ad7d7 ("net: hisilicon: add hix5hd2 mac driver")
