From 3e52be9bc501e577e2d8429bc2337bd979d38887 Mon Sep 17 00:00:00 2001 From: Zhang Zekun Date: Fri, 17 Jun 2022 10:39:25 +0100 Subject: [PATCH] media: rkvdec:Remove redundant memset As dma_alloc_coherent() will return a zeroed buffer, we don't need to memset the returned buffer. priv_tbl = dma_alloc_coherent() and count_tbl = dma_alloc_coherent() should be enough. -see commit 750afb08ca71 ("cross-tree: phase out dma_zalloc_coherent()") Signed-off-by: Zhang Zekun Reviewed-by: Dan Carpenter Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/staging/media/rkvdec/rkvdec-vp9.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/drivers/staging/media/rkvdec/rkvdec-vp9.c b/drivers/staging/media/rkvdec/rkvdec-vp9.c index 311a126..c2f42e7 100644 --- a/drivers/staging/media/rkvdec/rkvdec-vp9.c +++ b/drivers/staging/media/rkvdec/rkvdec-vp9.c @@ -1015,7 +1015,6 @@ static int rkvdec_vp9_start(struct rkvdec_ctx *ctx) vp9_ctx->priv_tbl.size = sizeof(*priv_tbl); vp9_ctx->priv_tbl.cpu = priv_tbl; - memset(priv_tbl, 0, sizeof(*priv_tbl)); count_tbl = dma_alloc_coherent(rkvdec->dev, RKVDEC_VP9_COUNT_SIZE, &vp9_ctx->count_tbl.dma, GFP_KERNEL); @@ -1026,7 +1025,6 @@ static int rkvdec_vp9_start(struct rkvdec_ctx *ctx) vp9_ctx->count_tbl.size = RKVDEC_VP9_COUNT_SIZE; vp9_ctx->count_tbl.cpu = count_tbl; - memset(count_tbl, 0, sizeof(*count_tbl)); rkvdec_init_v4l2_vp9_count_tbl(ctx); return 0; -- 2.7.4
