[ Upstream commit 632b746b108e3c62e0795072d00ed597371c738a ]
ACPICA commit 2ad4e6e7c4118f4cdfcad321c930b836cec77406
In some cases it is not practical nor useful to nag user about some firmware errors that they cannot fix. Add a macro that will print a warning or error only once to be used in these cases.
