From 7f9e88e6ef8c971f2c638b5ff7044c59b5d0f58d Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 25 Sep 2019 13:57:50 +0300 Subject: net: socionext: Fix a signedness bug in ave_probe() The "phy_mode" variable is an enum and in this context GCC treats it as an unsigned int so the error handling is never triggered.
