The older device property API is going to be removed.
Replacing the device_add_properties() call with software
node API equivalent device_create_managed_software_node().

Thanks!
I can take this through the ACPI tree if there are no objections.

Since this is related to device property API refactor, I'm
fine with it.
Lorenzo, what's your position?
Thanks

Is this really fixing anything ? I am not sure I understand what you
would like to achieve with this tag.

Right now it's not possible to simply remove the old API because some
of the maintainers want to take care of the conversion themselves, but
at the same time I also do not want to see any new releases of the
kernel that introduce more users for it. That's why it's a fix.

With the assumption that the above clarification is sufficient,
applied as 5.14 material, thanks!
