From 1653268b1b538981df9bb85d637456530938be6c Mon Sep 17 00:00:00 2001 From: Julia Lawall <julia@diku.dk> Date: Wed, 10 Mar 2010 22:18:13 +0100 Subject: driver core: module.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/) // <smpl> @@ expression a,flag; expression list args; statement S; @@ a = - \(kmalloc\|kzalloc\)(...,flag) + kasprintf(flag,args) <... when != a if (a == NULL || ...) S ...> - sprintf(a,args); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> --- drivers/base/module.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'drivers') diff --git a/drivers/base/module.c b/drivers/base/module.c index f32f2f9b7be..db930d3ee31 100644 --- a/drivers/base/module.c +++ b/drivers/base/module.c @@ -15,12 +15,10 @@ static char *make_driver_name(struct device_driver *drv) { char *driver_name; - driver_name = kmalloc(strlen(drv->name) + strlen(drv->bus->name) + 2, - GFP_KERNEL); + driver_name = kasprintf(GFP_KERNEL, "%s:%s", drv->bus->name, drv->name); if (!driver_name) return NULL; - sprintf(driver_name, "%s:%s", drv->bus->name, drv->name); return driver_name; } -- cgit v1.2.3-70-g09d2
