Three small fixes, all in drivers.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
Michael Kelley (1):
scsi: storvsc: Limit max_sectors for virtual Fibre Channel devices
Steffen Maier (1):
scsi: zfcp: Defer fc_rport blocking until after ADISC response
Yang Yingliang (1):
scsi: pm80xx: Fix error return code in pm8001_pci_probe()
