From 0d9ffc979f761c091a23020692b3502fa776eac0 Mon Sep 17 00:00:00 2001 From: Alexandru Gheorghiu Date: Mon, 25 Mar 2013 15:46:49 +0200 Subject: [PATCH] sound: oss: uart401: Used kmemdup instead of kmalloc and memcpy Used kmemdup instead of replicating it's behaviour with kmalloc followed by memcpy. Patch found using coccinelle.
