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

Pull SCSI fixes from James Bottomley:
 "This is a set of 12 fixes including the mpt3sas one that was causing
  hangs on ATA passthrough.

  The others are a couple of zoned block device fixes, a SAS device
  detection bug which lead to SATA drives not being matched to bays, two
  qla2xxx MSI fixes, a qla2xxx req for rsp confusion caused by cut and
  paste, and a few other minor fixes"
