commit ba3224db78034435e9ff0247277cce7c7bb1756c upstream.
The index for the elements of the ACPI object we dereference was static. This means that if we called the function twice we wouldn't start from 3 again, but rather from the latest index we reached in the previous call. This was dutifully reported by KASAN.
Fix this.
