Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"This is a set of 13 fixes, a MAINTAINERS update and a sparse update.
The fixes are mostly correct value initialisations, avoiding NULL
derefs and some uninitialised pointer avoidance.
All the patches have been incubated in -next for a few days. The
final patch (use the scsi data buffer length to extract transfer size)
has been rebased to add a cc to stable, but only the commit message
has changed"
