The current code expects the type of the value to be an integer type, instead the value passed to the macro is a pointer. Ensure the size comparison uses the correct pointer type to choose the max value, instead of using the integer type.
Fixes: 923044133367 ("ACPI: property: Unify integer value reading functions")
