Subject: [PATCH net] enetc: Fix a signedness bug in enetc_of_get_phy()
Date: Wed, 25 Sep 2019 13:57:14 +0300 [thread overview]
Message-ID: <20190925105714.GF3264@mwanda> (raw)
The "priv->if_mode" is type phy_interface_t which is an enum. In this
context GCC will treat the enum as an unsigned int so this error
handling is never triggered.
Fixes: d4fd0404c1c9 ("enetc: Introduce basic PF and VF ENETC ethernet drivers")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
