Merge tag 'char-misc-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver updates from Greg KH:
 "Here is the large set of char/misc and other driver subsystem changes
  for 6.2-rc1. Nothing earth-shattering in here at all, just a lot of
  new driver development and minor fixes.

  Highlights include:

   - fastrpc driver updates

   - iio new drivers and updates

   - habanalabs driver updates for new hardware and features

   - slimbus driver updates

   - speakup module parameters added to aid in boot time configuration

   - i2c probe_new conversions for lots of different drivers

   - other small driver fixes and additions

  One semi-interesting change in here is the increase of the number of
  misc dynamic minors available to 1048448 to handle new huge-cpu
  systems.

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