Pull misc driver fixes from Greg KH:
 "Here are some small char/misc/iio fixes for 6.12-rc6 that resolve
  some reported issues. Included in here are the following:

   - small IIO driver fixes for many reported issues

   - mei driver fix for a suddenly much reported issue for an "old"
     issue.

   - MAINTAINERS update for a developer who has moved companies and
     forgot to update their old entry.

  All of these have been in linux-next this week with no reported
  issues"
