Merge tag 'char-misc-6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char / misc / IIO / other driver updates from Greg KH:
 "Here is the big set of char/misc/iio and other smaller driver
  subsystems for 6.17-rc1. It's a big set this time around, with the
  huge majority being in the iio subsystem with new drivers and dts
  files being added there.

  Highlights include:
   - IIO driver updates, additions, and changes making more code const
     and cleaning up some init logic
   - bus_type constant conversion changes
   - misc device test functions added
   - rust miscdevice minor fixup
   - unused function removals for some drivers
   - mei driver updates
   - mhi driver updates
   - interconnect driver updates
   - Android binder updates and test infrastructure added
   - small cdx driver updates
   - small comedi fixes
   - small nvmem driver updates
   - small pps driver updates
   - some acrn virt driver fixes for printk messages
   - other small driver updates

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