From 810bf11033637a2069952afb9c37f3afd3bbfe41 Mon Sep 17 00:00:00 2001 From: Amitoj Kaur Chawla Date: Thu, 23 Jun 2016 10:19:37 +0530 Subject: tipc: Use kmemdup instead of kmalloc and memcpy Replace calls to kmalloc followed by a memcpy with a direct call to kmemdup. The Coccinelle semantic patch used to make this change is as follows: @@ expression from,to,size,flag; statement S; @@ - to = \(kmalloc\|kzalloc\)(size,flag); + to = kmemdup(from,size,flag); if (to==NULL || ...) S - memcpy(to, from, size); Signed-off-by: Amitoj Kaur Chawla Acked-by: Ying Xue Signed-off-by: David S.
