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> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Boris Brezillon <boris.brezillon@free-electrons.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
