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 user visible fixes (excepting one format string
  change).

  Four of the qla2xxx fixes only affect the firmware dump path, but it's
  still important to the enterprise. The rest are various NULL pointer
  crash conditions or outright driver hangs"
