[ Upstream commit f486893288f3e9b171b836f43853a6426515d800 ]
mptlan_probe() calls mpt_register_lan_device() which initializes the
&priv->post_buckets_task workqueue. A call to
mpt_lan_wake_post_buckets_task() will subsequently start the work.
During driver unload in mptlan_remove() the following race may occur:
CPU0 CPU1
|mpt_lan_post_receive_buckets_work()
mptlan_remove() |
free_netdev() |
kfree(dev); |
|
| dev->mtu
| //use
Fix this by finishing the work prior to cleaning up in mptlan_remove().
[mkp: we really should remove mptlan instead of attempting to fix it]
