Two small fixes, both in drivers (ufs and scsi_debug).
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
John Garry (1):
scsi: scsi_debug: Fix do_device_access() handling of unexpected SG copy length
Peter Wang (1):
scsi: ufs: core: Fix another deadlock during RTC update
