Subject: [PATCH] ACPICA: Use acpi_os_allocate_zeroed
Date: Mon, 20 Jun 2016 11:22:35 +0530 [thread overview]
Message-ID: <20160620055234.GA3104@amitoj-Inspiron-3542> (raw)
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));
