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, mpi3mr, libsas).

The major update (which causes a conflict with block, see below) is
Christoph removing the queue limits and their associated block
helpers.

The remaining patches are assorted minor fixes and deprecated function
updates plus a bit of constification"
