Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"The usual driver updates (ufs, qla2xxx, tcmu, ibmvfc, lpfc, smartpqi,
hisi_sas, qedi, qedf, mpt3sas) and minor bug fixes.
There are only three core changes: adding sense codes, cleaning up
noretry and adding an option for limitless retries"
