Merge tag 'scsi-for-linus' 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 drivers: arcmsr, qla2xx, lpfc,
  ufs, mpt3sas, hisi_sas.

  In addition we have removed several really old drivers: sym53c416,
  NCR53c406a, fdomain, fdomain_cs and removed the old scsi_module.c
  initialization from all remaining drivers.

  Plus an assortment of bug fixes, initialization errors and other minor
  fixes"
