Merge tag 'char-misc-6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char / misc / IIO driver updates from Greg KH:
 "Here is the big set of char, misc, iio, and other smaller driver
  subsystems for 6.15-rc1. Lots of stuff in here, including:

   - loads of IIO changes and driver updates

   - counter driver updates

   - w1 driver updates

   - faux conversions for some drivers that were abusing the platform
     bus interface

   - coresight driver updates

   - rust miscdevice binding updates based on real-world-use

   - other minor driver updates

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