Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"This is the first sweep of mostly minor fixes. There's one security
one: the read past the end of a buffer in qedf, and a panic fix for
lpfc SLI-3 adapters, but the rest are a set of include and build
dependency tidy ups and assorted other small fixes and updates"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: pmcraid: remove redundant check to see if request_size is less than zero
