3.11.10.10 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Tyler Stachecki <tstac...@binghamton.edu>
commit af61e27c3f77c7623b5335590ae24b6a5c323e22 upstream.
On suspend, _scsih_suspend calls mpt2sas_base_free_resources, which
in turn calls pci_disable_device if the device is enabled prior to
suspending. However, _scsih_suspend also calls pci_disable_device
itself.
Thus, in the event that the device is enabled prior to suspending,
pci_disable_device will be called twice. This patch removes the
duplicate call to pci_disable_device in _scsi_suspend as it is both
unnecessary and results in a kernel oops.
