Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"This is mostly updates of the usual suspects: lpfc, qla2xxx, hisi_sas,
megaraid_sas, pm80xx, mpt3sas, be2iscsi, hpsa. and a host of minor
updates.
There's no major behaviour change or additions to the core in all of
this, so the potential for regressions should be small (biggest
potential being in the scsi error handler changes)"
