Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley: "Two simple fixes. One prevents a soft lockup on some target removal scenarios and the other prevents us trying to probe the marvell console device, which causes it to time out and need the bus resetting" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: fix soft lockup in scsi_remove_target() on module removal SCSI: Add Marvell configuration device to VPD blacklist
