[PATCH] ddbridge: Replace vmalloc with vzalloc

From: Amitoj Kaur Chawla
Date: Mon Jun 20 2016 - 01:56:21 EST


vzalloc combines vmalloc and memset 0.

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

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