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"
