Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fix from James Bottomley:
"A single bug fix for hpsa.
The user visible consequences aren't clear, but the ioaccel2 raid
acceleration may misfire on the malformed request assuming the payload
is big enough to require chaining (more than 31 sg entries)"
