In the Linux kernel, the following vulnerability has been resolved:
octeon_ep: cancel queued works in probe error path
If it fails to get the devices's MAC address, octep_probe exits while
leaving the delayed work intr_poll_task queued. When the work later
runs, it's a use after free.
Move the cancelation of intr_poll_task from octep_remove into
octep_device_cleanup. This does not change anything in the octep_remove
flow, but octep_device_cleanup is called also in the octep_probe error
path, where the cancelation is needed.
Note that the cancelation of ctrl_mbox_task has to follow
intr_poll_task's, because the ctrl_mbox_task may be queued by
intr_poll_task.
