Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull more SCSI updates from James Bottomley:
"These are mostly minor updates.
There are two drivers (lpfc and mpi3mr) which missed the initial
pull and a core change to retry a start/stop unit which affect
suspend/resume"
