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 (ufs, pm80xx, lpfc,
mpi3mr, mpt3sas, hisi_sas, libsas) and minor updates and bug fixes.
The most impactful change is likely the switch from GFP_DMA to
GFP_KERNEL in a bunch of drivers, but even that shouldn't affect too
many people"
