From 7a12f4b50dad4fdffd218c6fba6b9564bf86185e Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 1 Jul 2010 01:52:33 -0300 Subject: [PATCH] V4L/DVB: drivers/media/video/zoran: 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 || ...) S - memcpy(to, from, size); // Signed-off-by: Julia Lawall Signed-off-by: Douglas Schilling Landgraf Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/zoran/videocodec.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/drivers/media/video/zoran/videocodec.c b/drivers/media/video/zoran/videocodec.c index cf24956f3204..c01071635290 100644 --- a/drivers/media/video/zoran/videocodec.c +++ b/drivers/media/video/zoran/videocodec.c @@ -107,15 +107,14 @@ videocodec_attach (struct videocodec_master *master) if (!try_module_get(h->codec->owner)) return NULL; - codec = - kmalloc(sizeof(struct videocodec), GFP_KERNEL); + codec = kmemdup(h->codec, sizeof(struct videocodec), + GFP_KERNEL); if (!codec) { dprintk(1, KERN_ERR "videocodec_attach: no mem\n"); goto out_module_put; } - memcpy(codec, h->codec, sizeof(struct videocodec)); snprintf(codec->name, sizeof(codec->name), "%s[%d]", codec->name, h->attached); -- GitLab
