Merge tag 'char-misc-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc and other driver updates from Greg KH:
"Here is the large set of char/misc and other small driver subsystem
changes for 6.1-rc1. Loads of different things in here:
- IIO driver updates, additions, and changes. Probably the largest
part of the diffstat
- habanalabs driver update with support for new hardware and
features, the second largest part of the diff.
- fpga subsystem driver updates and additions
- mhi subsystem updates
- Coresight driver updates
- gnss subsystem updates
- extcon driver updates
- icc subsystem updates
- fsi subsystem updates
- nvmem subsystem and driver updates
- misc driver updates
- speakup driver additions for new features
- lots of tiny driver updates and cleanups
All of these have been in the linux-next tree for a while with no
reported issues"
