From: Rafael J. Wysocki <[email protected]> The correct scope for looking up the objects to generate data packages for data-only subnodes pointed to by another data-only subnode is the scope of the parent of that subnode and not the scope containing the _DSD object at the top of the hierarchy (the latter works only if all of the objects returning data-only subnode packages in a given hierarchy are in the same scope).
Fix the code to work as expected. Fixes: 445b0eb058f5 (ACPI / property: Add support for data-only subnodes) Signed-off-by: Rafael J. Wysocki <[email protected]> --- On top of linux-next.
