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"
