[PATCH] ACPICA: Use acpi_os_allocate_zeroed

[Amitoj Kaur Chawla]

acpi_os_allocate_zeroed combines acpi_os_allocate and memset 0.

The Coccinelle semantic patch used to make this change is as follows:
@@
type T;
T *d;
expression e;
statement S;
@@

        d =
-            acpi_os_allocate
+            acpi_os_allocate_zeroed
             (...);
        if (!d) S
-       memset(d, 0, sizeof(T));
