From 6dfeb11a4b48e4994ac9e22eef5720f17d1f3502 Mon Sep 17 00:00:00 2001 From: zhong jiang Date: Tue, 18 Sep 2018 23:35:32 +0800 Subject: [PATCH] drm/amdkfd: Use kmemdup instead of duplicating its function kmemdup has implemented the function that kmalloc() + memcpy(). We prefer to kmemdup rather than code opened implementation.
