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 is a fatal section mismatch (reference to init
  after it's discarded) and the other two are iscsi locking fixes"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: NCR5380: no longer mark irq probing as __init
  scsi: be2iscsi: Replace _bh with _irqsave/irqrestore
  scsi: libiscsi: Fix locking in __iscsi_conn_send_pdu
