Subject: [GIT PULL] final round of SCSI updates for the 4.13+ merge window

A tiny update: one patch corrects a Kconfig problem with the shift of
the SAS SMP code to BSG and the other removes a vestige of user space
target mode.

The patch is available here:

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

The short changelog is:

Arnd Bergmann (1):
      scsi: scsi_transport_sas: select BLK_DEV_BSGLIB

Bart Van Assche (1):
      scsi: Remove Scsi_Host.uspace_req_q

And the diffstat:

 drivers/scsi/Kconfig     | 2 +-
 drivers/scsi/hosts.c     | 8 --------
 include/scsi/scsi_host.h | 6 ------
 3 files changed, 1 insertion(+), 15 deletions(-)

With full diff below.
