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 drivers: UFS, esp_scsi, NCR5380,
  qla2xxx, lpfc, libsas, hisi_sas.

  In addition there's a set of mostly small updates to the target
  subsystem a set of conversions to the generic DMA API, which do have
  some potential for issues in the older drivers but we'll handle those
  as case by case fixes.

  A new myrs driver for the DAC960/mylex raid controllers to replace the
  block based DAC960 which is also being removed by Jens in this merge
  window.

  Plus the usual slew of trivial changes"

[ "myrs" stands for "MYlex Raid Scsi". Obviously. Silly of me to even
  wonder. There's also a "myrb" driver, where the 'b' stands for
  'block'. Truly, somebody has got mad naming skillz. - Linus ]
