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;
+ }
