Merge tag 'char-misc-6.12-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull misc driver fixes from Greg KH:
 "Here are a number of small char/misc/iio driver fixes for 6.12-rc4:

   - loads of small iio driver fixes for reported problems

   - parport driver out-of-bounds fix

   - Kconfig description and MAINTAINERS file updates

  All of these, except for the Kconfig and MAINTAINERS file updates have
  been in linux-next all week. Those other two are just documentation
  changes and will have no runtime issues and were merged on Friday"
