Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI fixes from James Bottomley:
 "Two small fixes.

  One prevents timeouts on mpt3sas when trying to use the secure erase
  protocol which causes the erase protocol to be aborted. The second is
  a regression in a prior fix which causes all commands to abort during
  PCI extended error recovery, which is incorrect because PCI EEH is
  independent from what's happening on the FC transport"
