Five small fixes: four in drivers: hisi_sas: fix internal queue
timeout, be2iscsi: revert a prior fix causing problems, bnx2i: add
missing dependency, storvsc: late arriving revert of a problem fix, and
one in the core. The core one is a minor change to stop paying
attention to the busy count when returning out of resources because
there's a race window where the queue might not restart due to missing
returning I/O.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
Andrea Parri (Microsoft) (1):
Revert "scsi: storvsc: Validate length of incoming packet in storvsc_on_channel_callback()"
Dan Carpenter (1):
scsi: be2iscsi: Revert "Fix a theoretical leak in beiscsi_create_eqs()"
Ming Lei (1):
scsi: core: Fix race between handling STS_RESOURCE and completion
Randy Dunlap (1):
scsi: bnx2i: Requires MMU
Xiang Chen (1):
scsi: hisi_sas: Select a suitable queue for internal I/Os
