Pull SCSI fixes from James Bottomley:
 "Three HBA driver and one upper level driver (sg) fix.

  The sg change is the largest, but that results mostly from moving code
  to avoid the described race condition"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: ufs: core: Add ufshcd_update_evt_hist() for UFS suspend error
