Subject: [PATCH AUTOSEL 4.9 203/251] net: hisilicon: Fix signedness bug in hix5hd2_dev_probe()
From: Dan Carpenter <dan.carpenter@...cle.com>
[ Upstream commit 002dfe8085255b7bf1e0758c3d195c5412d35be9 ]
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")
