From 87575437d8173c7da48a4dee25399807c7bec9cb Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 26 May 2010 14:43:55 -0700 Subject: [PATCH] drivers/char/ppdev.c: use kasprintf kasprintf combines kmalloc and sprintf, and takes care of the size calculation itself. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ expression a,flag; expression list args; statement S; @@ a = - \(kmalloc\|kzalloc\)(...,flag) + kasprintf(flag,args) <... when != a if (a == NULL || ...) S ...> - sprintf(a,args); // Signed-off-by: Julia Lawall Cc: Michael Buesch Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/char/ppdev.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/drivers/char/ppdev.c b/drivers/char/ppdev.c index fdd37543aa79..02abfddce45a 100644 --- a/drivers/char/ppdev.c +++ b/drivers/char/ppdev.c @@ -287,12 +287,10 @@ static int register_device (int minor, struct pp_struct *pp) char *name; int fl; - name = kmalloc (strlen (CHRDEV) + 3, GFP_KERNEL); + name = kasprintf(GFP_KERNEL, CHRDEV "%x", minor); if (name == NULL) return -ENOMEM; - sprintf (name, CHRDEV "%x", minor); - port = parport_find_number (minor); if (!port) { printk (KERN_WARNING "%s: no associated port!\n", name); -- 2.20.1
