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

Pull more SCSI updates from James Bottomley:
 "This is a set of minor fixes and clean ups in the core and various
  drivers.

  The only core change in behaviour is the I/O retry for spinup notify,
  but that shouldn't impact anything other than the failing case"
