Re: [PATCH] scsi: lpfc: Fix crash on PCI hotplug remove path

[James Smart <james.smart@broadcom.com>]

Actually, I think we solved this in a better manner in this patch in the 
11.4.0.0 patch set:
   PATCH 10/15] lpfc: Fix crash on powering off BFS VM with passthrough 
device
   http://marc.info/?l=linux-scsi&m=149621070910290&w=2

See if the above patch fixes your error.
