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 driver suspects: arcmsr,
  scsi_debug, mpt3sas, lpfc, cxlflash, qla2xxx, aacraid, megaraid_sas,
  hisi_sas.

  We also have a rework of the libsas hotplug handling to make it more
  robust, a slew of 32 bit time conversions and fixes, and a host of the
  usual minor updates and style changes. The biggest potential for
  regressions is the libsas hotplug changes, but so far they seem stable
  under testing"
