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

Pull first round of SCSI updates from James Bottomley:
 "This patch set is a set of driver updates (ufs, zfcp, lpfc, mpt2/3sas,
  qla4xxx, qla2xxx [adding support for ISP8044 + other things]).

  We also have a new driver: esas2r which has a number of static checker
  problems, but which I expect to resolve over the -rc course of 3.12
  under the new driver exception.

  We also have the error return that were discussed at LSF"
