Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull final round of SCSI updates from James Bottomley:
"Sorry for the delay in this patch which was mostly caused by getting
the merger of the mpt2/mpt3sas driver, which was seen as an essential
item of maintenance work to do before the drivers diverge too much.
Unfortunately, this caused a compile failure (detected by linux-next),
which then had to be fixed up and incubated.
In addition to the mpt2/3sas rework, there are updates from pm80xx,
lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc and ufs plus
an assortment of changes including some year 2038 issues, a fix for a
remove before detach issue in some drivers and a couple of other minor
issues"
* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (141 commits)
