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 the usual driver updates (ufs, qla2xxx, smartpqi,
target, zfcp, fnic, mpt3sas, ibmvfc) plus a load of cleanups, a major
power management rework and a load of assorted minor updates.
There are a few core updates (formatting fixes being the big one) but
nothing major this cycle"
