Merge tag 'staging-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging/IIO updates from Greg KH:
 "Here is the big staging and IIO driver update for 4.18-rc1.

  It was delayed as I wanted to make sure the final driver deletions did
  not cause any major merge issues, and all now looks good.

  There are a lot of patches here, just over 1000. The diffstat summary
  shows the major changes here:

	1007 files changed, 16828 insertions(+), 227770 deletions(-)

  Because of this, we might be close to shrinking the overall kernel
  source code size for two releases in a row.

  There was loads of work in this release cycle, primarily:

   - tons of ks7010 driver cleanups

   - lots of mt7621 driver fixes and cleanups

   - most driver cleanups

   - wilc1000 fixes and cleanups

   - lots and lots of IIO driver cleanups and new additions

   - debugfs cleanups for all staging drivers

   - lots of other staging driver cleanups and fixes, the shortlog has
     the full details.

  but the big user-visable things here are the removal of 3 chunks of
  code:

   - ncpfs and ipx were removed on schedule, no one has cared about this
     code since it moved to staging last year, and if it needs to come
     back, it can be reverted.

   - lustre file system is removed.

     I've ranted at the lustre developers about once a year for the past
     5 years, with no real forward progress at all to clean things up
     and get the code into the "real" part of the kernel.

     Given that the lustre developers continue to work on an external
     tree and try to port those changes to the in-kernel tree every once
     in a while, this whole thing really really is not working out at
     all. So I'm deleting it so that the developers can spend the time
     working in their out-of-tree location and get things cleaned up
     properly to get merged into the tree correctly at a later date.

  Because of these file removals, you will have merge issues on some of
  these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
  atomisp driver). Just delete those files, it's a simple merge :)

  All of this has been in linux-next for a while with no reported
  problems"
