Hi All,

A user report regarding "ACPI: \: Can't tag data node" error messages in dmesg
made me look at the ACPI property code and I've found a couple of issues in
it.

Also, it took me some time to figure out why the code was doing what it was
doing, so I decided to add some comments explaining it.

Finally, there's always something that can be cleaned up in every piece of
kernel code.

Hence, this series.

Please refer to the patch changelogs for details.

Thanks!
