Subject: [PATCH net] of: mdio: Fix a signedness bug in of_phy_get_and_connect()
Date: Wed, 25 Sep 2019 14:01:00 +0300 [thread overview]
Message-ID: <20190925110100.GL3264@mwanda> (raw)
The "iface" variable is an enum and in this context GCC treats it as
an unsigned int so the error handling is never triggered.
Fixes: b78624125304 ("of_mdio: Abstract a general interface for phy connect")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
