Merge tag 'char-misc-7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull Char/Misc/IIO/others driver updates from Greg KH:
 "Here is the big set of char/misc/android/iio and other small driver
  subsystem patches for 7.4-rc1. Loads of stuff in here, larger than
  normal. Highlights include:

   - removal of the C binder code, the rust version is stable and will
     be used going forward in a few billion devices. Great job by those
     developers

   - loads and loads of IIO driver updates and feature additions

   - speakup driver fixes and updates

   - mhi driver updates

   - mei driver updates

   - xillybus driver fixes

   - comedi driver fixes

   - lots of coresight driver updates

   - Interconnect driver updates

   - nvmem driver updates and fixes

   - slimbus driver updates and fixes

   - spmi driver updates and fixes

   - lots of tiny misc and char driver fixes based on people scanning
     for things

  All of these have been in linux-next for a while with no reported
  issues, other than a merge conflict with one of the rust tree files,
  which should be simple to resolve"
