Merge tag 'char-misc-6.7-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char / misc driver fixes from Greg KH:
 "Here are a small number of various driver fixes for 6.7-rc7 that
  normally come through the char-misc tree, and one debugfs fix as well.

  Included in here are:

   - iio and hid sensor driver fixes for a number of small things

   - interconnect driver fixes

   - brcm_nvmem driver fixes

   - debugfs fix for previous fix

   - guard() definition in device.h so that many subsystems can start
     using it for 6.8-rc1 (requested by Dan Williams to make future
     merges easier)

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