Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI fixes from James Bottomley:
 "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"

  scsi: core: Fix race between handling STS_RESOURCE and completion
