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.

The patch is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes

The short changelog is:

James Bottomley (1):
      scsi: fix soft lockup in scsi_remove_target() on module removal

Todd Fujinaka (1):
      SCSI: Add Marvell configuration device to VPD blacklist

And the diffstat:
