SCSI misc on 20190709
This is mostly update of the usual drivers: qla2xxx, hpsa, lpfc, ufs,
mpt3sas, ibmvscsi, megaraid_sas, bnx2fc and hisi_sas as well as the
removal of the osst driver (I heard from Willem privately that he
would like the driver removed because all his test hardware has
failed). Plus number of minor changes, spelling fixes and other
trivia.

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 update of the usual drivers: qla2xxx, hpsa, lpfc, ufs,
mpt3sas, ibmvscsi, megaraid_sas, bnx2fc and hisi_sas as well as the
removal of the osst driver (I heard from Willem privately that he
would like the driver removed because all his test hardware has
failed). Plus number of minor changes, spelling fixes and other
trivia.
The big merge conflict this time around is the SPDX licence tags.
Following discussion on linux-next, we believe our version to be more
accurate than the one in the tree, so the resolution is to take our
version for all the SPDX conflicts"
Note on the SPDX license tag conversion conflicts: the SCSI tree had
done its own SPDX conversion, which in some cases conflicted with the
treewide ones done by Thomas & co.
In almost all cases, the conflicts were purely syntactic: the SCSI tree
used the old-style SPDX tags ("GPL-2.0" and "GPL-2.0+") while the
treewide conversion had used the new-style ones ("GPL-2.0-only" and
"GPL-2.0-or-later").
In these cases I picked the new-style one.
In a few cases, the SPDX conversion was actually different, though. As
explained by James above, and in more detail in a pre-pull-request
thread:
"The other problem is actually substantive: In the libsas code Luben
Tuikov originally specified gpl 2.0 only by dint of stating:
* This file is licensed under GPLv2.
In all the libsas files, but then muddied the water by quoting GPLv2
verbatim (which includes the or later than language). So for these
files Christoph did the conversion to v2 only SPDX tags and Thomas
converted to v2 or later tags"
So in those cases, where the spdx tag substantially mattered, I took the
SCSI tree conversion of it, but then also took the opportunity to turn
the old-style "GPL-2.0" into a new-style "GPL-2.0-only" tag.
Similarly, when there were whitespace differences or other differences
to the comments around the copyright notices, I took the version from
the SCSI tree as being the more specific conversion.
Finally, in the spdx conversions that had no conflicts (because the
treewide ones hadn't been done for those files), I just took the SCSI
tree version as-is, even if it was old-style. The old-style conversions
are perfectly valid, even if the "-only" and "-or-later" versions are
perhaps more descriptive.
