Merge tag 'staging-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull IIO and staging driver updates from Greg KH:
 "Here is the big set of staging and IIO driver updates for 5.15-rc1.
  Also included in here are the counter driver subsystem updates as the
  IIO drivers needed them.

  Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
  driver and replaced it with a newer version of the driver that had
  been maintained out-of-tree by Larry with the end goal of actually
  being able to get this driver out of staging eventually. Despite that
  driver being "newer" the line count of this pull request is going up.

  Some drivers moved out of staging as well, which is always nice to
  see, that is why there are additions to the mfc and misc driver
  subsystems. All of these were acked by the various subsystem
  maintainers involved.

  But by far, as normal, it's coding style cleanups all over the
  drivers/staging/ tree in here.

  Full details of these changes are in the shortlog.

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

[ Note: the r8188eu merge clashed with commit 89939e890605 ("staging:
  rtlwifi: use siocdevprivate") from the networking tree. When resolving
  the issue, I noted that the whole r8188eu rtw_android code is dead
  since commit ae7471cae00a ("staging: r8188eu: remove rtw_ioctl
  function").

  End result: the merge resolution was to throw all of that away,
  rather than do the mindless fixup to code that isn't actually
  reachable                                               - Linus ]
