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

Pull SCSI updates from James Bottomley:
 "This is mostly updates of the usual suspects: lpfc, qla2xxx, hisi_sas,
  megaraid_sas, pm80xx, mpt3sas, be2iscsi, hpsa. and a host of minor
  updates.

  There's no major behaviour change or additions to the core in all of
  this, so the potential for regressions should be small (biggest
  potential being in the scsi error handler changes)"
