[PATCH 0/5] Use dma_pool_zalloc

From: Julia Lawall
Date: Fri Apr 29 2016 - 16:24:49 EST


Dma_pool_zalloc combines dma_pool_alloc and memset 0. The semantic patch
that makes this transformation is as follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
type T;
T *d;
expression e;
statement S;
@@

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

@@
expression d,e;
statement S;
@@

d =
- dma_pool_alloc
+ dma_pool_zalloc
(...);
if (!d) S
- memset(d, 0, sizeof(*d));
// </smpl>
