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

Pull SCSI fixes from James Bottomley:
 "Two driver fixes (zfcp and target core), one information leak in sg
  and one build clean up"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: sg: allocate with __GFP_ZERO in sg_build_indirect()
  scsi: core: clean up generated file scsi_devinfo_tbl.c
  scsi: target: tcmu: fix error resetting qfull_time_out to default
  scsi: zfcp: fix infinite iteration on ERP ready list
