Here is the big set of char/misc and other small driver subsystem
changes for 6.7-rc1. Included in here are:
- IIO subsystem driver updates and additions (largest part of this
pull request)
- FPGA subsystem driver updates
- Counter subsystem driver updates
- ICC subsystem driver updates
- extcon subsystem driver updates
- mei driver updates and additions
- nvmem subsystem driver updates and additions
- comedi subsystem dependency fixes
- parport driver fixups
- cdx subsystem driver and core updates
- splice support for /dev/zero and /dev/full
- other smaller driver cleanups
All of these have been in linux-next for a while with no reported
issues.
