[PATCH v1] ACPI: Property: Fix type detection of unified integer reading functions

From: Stefan Binding
Date: Fri Aug 12 2022 - 09:07:10 EST


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")
