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

Pull SCSI updates from James Bottomley:
 "This patch is the usual mix of driver updates (srp, ipr, scsi_debug,
  NCR5380, fnic, 53c974, ses, wd719x, hpsa, megaraid_sas).

  Of those, wd7a9x is new and 53c974 is a rewrite of the old tmscsim
  driver and the extensive work by Finn Thain rewrites all the NCR5380
  based drivers.

  There's also extensive infrastructure updates: a new logging
  infrastructure for sense information and a rewrite of the tagged
  command queue API and an assortment of minor updates"
