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

Pull SCSI fixes from James Bottomley:
 "Varions small  fixes, all  in drivers.

  Some of these arrived during the merge window and got held over to
  make sure of testing on the -rc tree.

  The biggest change is for standards conformance in the target driver,
  closely followed by a set of bug fixes in megaraid_sas"
