From 5d25fde23b3176c7f94d2a992cb9762707d7c2a0 Mon Sep 17 00:00:00 2001 From: Shyam Saini Date: Thu, 19 Jan 2017 13:45:34 -0800 Subject: [PATCH] drm/vmwgfx: Use kmemdup instead of kmalloc and memcpy When some other buffer is immediately copied into allocated region. Replace calls to kmalloc followed by a memcpy with a direct call to kmemdup.
