From: Rafael J. Wysocki <[email protected]> Quite a few users of ACPI objects want to log a warning message if the evaluation fails which is a repeating pattern, so introduce a helper function for that purpose and convert some code where it is open-coded to using it.
No intentional functional impact. Signed-off-by: Rafael J.
