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 <amitoj1606@gmail.com> Acked-by: Ying Xue <ying.xue@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
