[PATCH] ACPICA: Use acpi_os_allocate_zeroed

From: Amitoj Kaur Chawla
Date: Sat Jun 18 2016 - 02:50:51 EST


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));
