Jesper Juhl d478376cb0 driver core: fix small mem leak in driver_add_kobj() 
The Coverity checker spotted that we leak the storage allocated to 'name' in
int driver_add_kobj().  The leak looks legit to me - this is the code :

int driver_add_kobj(struct device_driver *drv, struct kobject *kobj,
                    const char *fmt, ...)
{
        va_list args;
        char *name;
        int ret;

        va_start(args, fmt);
        name = kvasprintf(GFP_KERNEL, fmt, args);
        ^^^^^^^^ This dynamically allocates space...

        va_end(args);

        if (!name)
                return -ENOMEM;

        return kobject_add(kobj, &drv->p->kobj, "%s", name);
	^^^^^^^^ This neglects to free the space allocated
}

Inside kobject_add() a copy of 'name' will be made and used.  As far as I can
see, Coverity is correct in flagging this as a leak, but I'd like some
configmation before the patch is applied.

This should fix it.
