Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"This consists of a small set of driver updates (lpfc, ufs, mpt3sas
mpi3mr, iscsi target). Apart from that this is mostly small fixes with
very few core changes (the biggest one being VPD caching)"
