misc_register() in drivers/char/misc.c seems to have a problem.
int misc_register(struct miscdevice * misc) { static devfs_handle_t devfs_handle; - + struct miscdevice *c; + if (misc->next || misc->prev) return -EBUSY; down(&misc_sem); + c = misc_list.next; + + while ((c != &misc_list) && (c->minor != misc->minor)) + c = c->next; + if (c == &misc_list) {
This should be (c != &misc_list)
+ up(&misc_sem); + return -EBUSY; + }
