Merge tag 'char-misc-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull Char/Misc updates from Greg KH:
 "Here is the big set of char/misc and other driver subsystem updates
  for 6.5-rc1.

  Lots of different, tiny, stuff in here, from a range of smaller driver
  subsystems, including pulls from some substems directly:

   - IIO driver updates and additions

   - W1 driver updates and fixes (and a new maintainer!)

   - FPGA driver updates and fixes

   - Counter driver updates

   - Extcon driver updates

   - Interconnect driver updates

   - Coresight driver updates

   - mfd tree tag merge needed for other updates on top of that, lots of
     small driver updates as patches, including:

   - static const updates for class structures

   - nvmem driver updates

   - pcmcia driver fix

   - lots of other small driver updates and fixes

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