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

Pull SCSI fixes from James Bottomley:
 "All in drivers.

  The largest change is the ufs one which has to introduce a new
  function to check the power state before doing the update and the most
  widely encountered one is the obvious change to sg to not use
  GFP_ATOMIC"
