Merge tag 'staging-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging 

Pull staging and IIO updates from Greg KH:
 "Here is the "big" staging and IIO driver update for 4.15-rc1.

  Lots and lots of little changes, almost all minor code cleanups as the
  Outreachy application process happened during this development cycle.
  Also happened was a lot of IIO driver activity, and the typec USB code
  moving out of staging to drivers/usb (same commits are in the USB tree
  on a persistent branch to not cause merge issues.)

  Overall, it's a wash, I think we added a few hundred more lines than
  removed, but really only a few thousand were modified at all.

  All of these have been in linux-next for a while. There might be a
  merge issue with Al's vfs tree in the pi433 driver (take his changes,
  they are always better), and the media tree with some of the odd
  atomisp cleanups (take the media tree's version)"
