Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"Updates to the usual drivers (ufs, lpfc, qla2xxx, libsas).
The major core change is a rework to remove the two helpers around
scsi_execute_cmd and use it as the only submission interface along
with other minor fixes and updates"
