Merge tag 'driver-core-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"Here is the big set of driver core and debug printk changes for
6.1-rc1. Included in here is:
- dynamic debug updates for the core and the drm subsystem. The drm
changes have all been acked by the relevant maintainers
- kernfs fixes for syzbot reported problems
- kernfs refactors and updates for cgroup requirements
- magic number cleanups and removals from the kernel tree (they were
not being used and they really did not actually do anything)
- other tiny cleanups
All of these have been in linux-next for a while with no reported
issues"
