From 49b487c903e929d49c65fa52f104628743a98bc3 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Date: Sun, 6 Aug 2017 23:37:01 +0200 Subject: [PATCH] i40e: Fix a potential NULL pointer dereference If 'kzalloc()' fails, a NULL pointer will be dereferenced. Return an error code (-ENOMEM) instead.
