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

Pull SCSI updates from James Bottomley:
 "This patch set is a lot of driver updates for qla4xxx, bfa, hpsa,
  qla2xxx.  It also removes the aic7xxx_old driver (which has been
  deprecated for nearly a decade) and adds support for deadlines in
  error handling"
