From b24b1e4b1d6776ca12a57eff77956bce77b2e56f Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Wed, 7 Mar 2018 03:39:04 +0100 Subject: [PATCH] net: mvpp2x: add check after calloc After allocating plat the pointer is checked. Afterwards name is allocated and not checked. Add the missing check to avoid a possible NULL dereference.
