Merge tag 'char-misc-6.6-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver fixes from Greg KH:
 "Here is a small set of char/misc and other smaller driver subsystem
  fixes for 6.6-rc6. Included in here are:

   - lots of iio driver fixes

   - binder memory leak fix

   - mcb driver fixes

   - counter driver fixes

   - firmware loader documentation fix

   - documentation update for embargoed hardware issues

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