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

Pull SCSI fixes from James Bottomley:
 "I had actually prepared this fix set before I left for KS + Plumbers,
  so it's been incubating much longer than it should have.  I'll be
  picking up my three week backlog this week, so more fixes will then be
  forthcoming

  This set consist of three minor and one fairly major (the device not
  ready causing offlining problem which is a serious regression
  introduced by the media change update) fixes.

  Signed-off-by: James Bottomley <JBottomley@Parallels.com>"
