From f802912d42525eddb2e504b0b852539f46c8fd9d Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Thu, 25 Oct 2018 14:42:38 +0200 Subject: [PATCH] net: phy: genphy_10g_driver: Avoid NULL pointer dereference This driver got missed during the recent change of .features from a u32 to a pointer to a Linux bitmap. Change the initialisation from 0 to PHY_10GBIT_FEATURES so removing the danger of a NULL pointer dereference.
