Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"Four small fixes.
The be2iscsi is a potential device overrun in consistent memory, which
could have nasty consequences if the consistent allocations are
packed.
The hpsa one fixes a regression where older controllers can now get a
numbering clash between the first internal disk and the controller.
The libfc one is a regression in timespec conversions which causes a
user visible issue in a command line tool and the mpt3sas one fixes a
regression where the controller could remain permanently blocked after
an ATA pass through command followed by a reset"
