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

Pull SCSI updates from James Bottomley:
 "This update includes the usual round of major driver updates (hpsa,
  be2iscsi, hisi_sas, zfcp, cxlflash). There's a new incarnation of hpsa
  called smartpqi for which a driver is added, there's some cleanup work
  of the ibm vscsi target and updates to libfc, plus a whole host of
  minor fixes and updates and finally the removal of several ISA drivers
  which seem not to have been used for years"
