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

Pull first round of SCSI updates from James Bottomley:
 "This patch consists of the usual driver updates (megaraid_sas,
  scsi_debug, qla2xxx, qla4xxx, lpfc, bnx2fc, be2iscsi, hpsa, ipr) plus
  an assortment of minor fixes and the first precursors of SCSI-MQ (the
  code path simplifications) and the bug fix for the USB oops on remove
  (which involves an infrastructure change, so is sent via the main tree
  with a delayed backport after a cycle in which it is shown to
  introduce no new bugs)"
