From d80f2666b5373f195deae57c9f33a5abb8053d37 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 15 May 2010 23:23:31 +0200 Subject: drivers/mtd: 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: David Woodhouse --- drivers/mtd/mtdconcat.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'drivers/mtd') diff --git a/drivers/mtd/mtdconcat.c b/drivers/mtd/mtdconcat.c index db6de74..7e07562 100644 --- a/drivers/mtd/mtdconcat.c +++ b/drivers/mtd/mtdconcat.c @@ -183,10 +183,9 @@ concat_writev(struct mtd_info *mtd, const struct kvec *vecs, } /* make a copy of vecs */ - vecs_copy = kmalloc(sizeof(struct kvec) * count, GFP_KERNEL); + vecs_copy = kmemdup(vecs, sizeof(struct kvec) * count, GFP_KERNEL); if (!vecs_copy) return -ENOMEM; - memcpy(vecs_copy, vecs, sizeof(struct kvec) * count); entry_low = 0; for (i = 0; i < concat->num_subdev; i++) { -- cgit v1.1
