From 472d640bd0fe5b28332b277316cff1dadf40d083 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Fri, 29 Apr 2016 22:09:11 +0200 Subject: [PATCH] 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/) // @@ expression d,e; statement S; @@ d = - dma_pool_alloc + dma_pool_zalloc (...); if (!d) S - memset(d, 0, sizeof(*d)); // Signed-off-by: Julia Lawall Acked-by: Boris Brezillon Signed-off-by: Herbert Xu --- drivers/crypto/marvell/tdma.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/drivers/crypto/marvell/tdma.c b/drivers/crypto/marvell/tdma.c index 7642798..0ad8f1e 100644 --- a/drivers/crypto/marvell/tdma.c +++ b/drivers/crypto/marvell/tdma.c @@ -99,12 +99,11 @@ mv_cesa_dma_add_desc(struct mv_cesa_tdma_chain *chain, gfp_t flags) struct mv_cesa_tdma_desc *new_tdma = NULL; dma_addr_t dma_handle; - new_tdma = dma_pool_alloc(cesa_dev->dma->tdma_desc_pool, flags, - &dma_handle); + new_tdma = dma_pool_zalloc(cesa_dev->dma->tdma_desc_pool, flags, + &dma_handle); if (!new_tdma) return ERR_PTR(-ENOMEM); - memset(new_tdma, 0, sizeof(*new_tdma)); new_tdma->cur_dma = dma_handle; if (chain->last) { chain->last->next_dma = cpu_to_le32(dma_handle); -- 2.7.4
