From 492b3c0c9c0b1da49890c1954746ce24a2e311f2 Mon Sep 17 00:00:00 2001 From: Himanshu Jha Date: Mon, 11 Sep 2017 18:07:26 +0530 Subject: [PATCH 0941/4131] drm/amd/powerplay: remove unnecessary call to memset call to memset to assign 0 value immediately after allocating memory with kzalloc is unnecesaary as kzalloc allocates the memory filled with 0 value.
