Merge tag 'char-misc-6.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char / miscdriver fixes from Greg KH:
 "Here is a small set of char/misc and IIO driver fixes for 6.8-rc5.

  Included in here are:

   - lots of iio driver fixes for reported issues

   - nvmem device naming fixup for reported problem

   - interconnect driver fixes for reported issues

  All of these have been in linux-next for a while with no reported the
  issues (the nvmem patch was included in a different branch in
  linux-next before sent to me for inclusion here)"
