[PATCH AUTOSEL 4.19 565/671] net: netsec: Fix signedness bug in netsec_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ 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")
