[PATCH] ACPICA: Use acpi_os_allocate_zeroed
From: Amitoj Kaur Chawla
Date: Mon Jun 20 2016 - 01:55:22 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));
