Merge tag 'staging-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging driver updates from Greg KH:
 "Here is the big set of staging driver updates and cleanups for
  5.16-rc1.

  Overall we ended up removing a lot of code this time, a bit over
  20,000 lines are now gone thanks to a lot of cleanup work by many
  developers.

  Nothing huge in here functionality wise, just loads of cleanups:

   - r8188eu driver major cleanups and removal of unused and dead code

   - wlan-ng minor cleanups

   - fbtft driver cleanups

   - most driver cleanups

   - rtl8* drivers cleanups

   - rts5208 driver cleanups

   - vt6655 driver cleanups

   - vc04_services drivers cleanups

   - wfx cleanups on the way to almost getting this merged out of
     staging (it's close!)

   - tiny mips changes needed for the mt7621 drivers, they have been
     acked by the respective subsystem maintainers to go through this
     tree.

  All of these have been in linux-next for a while with no reported
  issues"
