Merge tag 'char-misc-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc and other driver subsystem updates from Greg KH:
"Here is the big set of char/misc and a number of other driver
subsystem updates for 6.9-rc1. Included in here are:
- IIO driver updates, loads of new ones and evolution of existing ones
- coresight driver updates
- const cleanups for many driver subsystems
- speakup driver additions
- platform remove callback void cleanups
- mei driver updates
- mhi driver updates
- cdx driver updates for MSI interrupt handling
- nvmem driver updates
- other smaller driver updates and cleanups, full details in the
shortlog
All of these have been in linux-next for a long time with no reported
issue, other than a build warning for the speakup driver"
The build warning hits clang and is a gcc (and C23) extension, and is
fixed up in the merge.
