From 510e65dfb0e1817ef48c43839b8789131800a6f6 Mon Sep 17 00:00:00 2001 From: Muhammad Falak R Wani Date: Thu, 19 May 2016 16:45:29 +0530 Subject: [PATCH] drm/amd/powerplay/hwmgr: use kmemdup Use kmemdup when some other buffer is immediately copied into allocated region. It replaces call to allocation followed by memcpy, by a single call to kmemdup.
