Lion Vollnhals napsal(a):
This patch against 2.6.13-mm3 replaces malloc and memset with kzalloc in drivers/base/class.c .
Furthermore this patch fixes actually two bugs:
The memset arguments were occasionally swaped and therefore wrong.
Usage of kzalloc makes this code shorter and more bugfree.
Please apply.

maybe, the better way is to write `*cls' instead of `struct class',
better for further changes
if (!cls) {
retval = -ENOMEM;
goto error;
}
- memset(cls, 0x00, sizeof(struct class));
