Subject: [PATCH v1 3/4] ACPI: utils: Refine acpi_handle_list_equal() slightly

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

It is somewhat better to use the size of the first array element for
computing the size of the entire array than to rely on the array
element data type definition knowledge and the former is also
consistent with the array allocation in acpi_evaluate_reference(),
so modify the code accordingly.

No intentional functional impact.
