crypto: marvell/cesa - Use dma_pool_zalloc
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>
@@
expression d,e;
statement S;
@@
d =
- dma_pool_alloc
+ dma_pool_zalloc
(...);
if (!d) S
- memset(d, 0, sizeof(*d));
// </smpl>
