SCSI misc on 20130903 

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 updates that were discussed at LSF.
