From 2b3c543a839cafeb3edd7e1a2202d86318801fd9 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 1 Jul 2010 01:41:44 -0300 Subject: [PATCH] V4L/DVB: drivers/media/video/tlg2300: Use kmemdup Use kmemdup when some other buffer is immediately copied into the allocated region. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ expression from,to,size,flag; statement S; @@ - to = \(kmalloc\|kzalloc\)(size,flag); + to = kmemdup(from,size,flag); if (to==NULL || ...)
