…t/jejb/scsi

Pull SCSI fixes from James Bottomley:
 "I'd like to say these were a set of regressions for the recent merge
  window code.  Unfortunately, they all predate the merge window code
  (stable cc'd).

  There are two fixes for data integrity (mostly only showing up on
  module removal), an mvsas crash with expander attached SATA devices
  which goes back to the dawn of the driver but is only just being
  picked up as sas expanders become a standard item in low end server
  hardware, an am53c974 one because the interrupt data isn't fully
  initialised before the line is and a megaraid_sas one because it uses
  smp_processor_id() to select MSI-X queues and that now triggers a
  WARN_ON()"

  mvsas: fix panic on expander attached SATA devices
  am53c974: Fix crash during modprobe
