Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
:This series consists of the usual driver updates (qla2xxx, ufs, zfcp,
target, scsi_debug, lpfc, qedi, qedf, hisi_sas, mpt3sas) plus a host
of other minor updates.
There are no major core changes in this series apart from a
refactoring in scsi_lib.c"
