One target driver fix and one scsi-generic one.  The latter is 10 lines
because the problem lock has to be dropped and re-taken around the call
causing the sleep in atomic.

The patch is available here:

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

The short changelog is:

Bart Van Assche (1):
      scsi: sg: Do not sleep in atomic context

Hamza Mahfooz (1):
      scsi: target: tcm_loop: Fix segfault in tcm_loop_tpg_address_show()
