Merge tag 'driver-core-5.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core and documentation fixes from Greg KH:
"Here is one tiny debugfs change to fix up an API where the last user
was successfully fixed up in 5.10-rc1 (so it couldn't be merged
earlier), and a much larger Documentation/ABI/ update to the files so
they can be automatically parsed by our tools.
The Documentation/ABI/ updates are just formatting issues, small ones
to bring the files into parsable format, and have been acked by
numerous subsystem maintainers and the documentation maintainer. I
figured it was good to get this into 5.10-rc2 to help wih the merge
issues that would arise if these were to stick in linux-next until
5.11-rc1.
The debugfs change has been in linux-next for a long time, and the
Documentation updates only for the last linux-next release"
