Fix the module init error handling. There are a bunch of goto labels for aborting the init procedure at different points and just undoing what needs undoing - they aren't all in the right places, however. This can lead to an oops like the following: BUG: unable to handle kernel NULL pointer dereference at 0000000000000020 IP: [<ffffffff81042a31>] destroy_workqueue+0x17/0xc0 ...
