    Subject[PATCH AUTOSEL 4.19 565/671] net: netsec: Fix signedness bug in netsec_probe()
    Date
    From: Dan Carpenter <dan.carpenter@oracle.com>

    [ Upstream commit bd55f8ddbc437c225391ca8f487e7ec10243c4cc ]

    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")
