Merge tag 'char-misc-6.9-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc 

Pull char/misc driver fixes from Greg KH:
 "Here are some small char/misc/other driver fixes and new device ids
  for 6.9-rc7 that resolve some reported problems.

  Included in here are:

   - iio driver fixes

   - mei driver fix and new device ids

   - dyndbg bugfix

   - pvpanic-pci driver bugfix

   - slimbus driver bugfix

   - fpga new device id

  All have been in linux-next with no reported problems"
