From e283655b5abe26462d53d5196f186c5e8863af3b Mon Sep 17 00:00:00 2001 From: Aaro Koskinen Date: Fri, 16 Mar 2018 22:17:28 +0200 Subject: [PATCH] drivers: macintosh: rack-meter: really fix bogus memsets We should zero an array using sizeof instead of number of elements. Fixes the following compiler (GCC 7.3.0) warnings: drivers/macintosh/rack-meter.c: In function 'rackmeter_do_pause': drivers/macintosh/rack-meter.c:157:2: warning: 'memset' used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size] drivers/macintosh/rack-meter.c:158:2: warning: 'memset' used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size] Fixes: 4f7bef7a9f69 ("drivers: macintosh: rack-meter: fix bogus memsets") Reported-by: Stephen Rothwell Signed-off-by: Aaro Koskinen Signed-off-by: Michael Ellerman --- drivers/macintosh/rack-meter.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/macintosh/rack-meter.c b/drivers/macintosh/rack-meter.c index 190c9efeace5..1f29d2413c74 100644 --- a/drivers/macintosh/rack-meter.c +++ b/drivers/macintosh/rack-meter.c @@ -154,8 +154,8 @@ static void rackmeter_do_pause(struct rackmeter *rm, int pause) DBDMA_DO_STOP(rm->dma_regs); return; } - memset(rdma->buf1, 0, ARRAY_SIZE(rdma->buf1)); - memset(rdma->buf2, 0, ARRAY_SIZE(rdma->buf2)); + memset(rdma->buf1, 0, sizeof(rdma->buf1)); + memset(rdma->buf2, 0, sizeof(rdma->buf2)); rm->dma_buf_v->mark = 0; -- 2.30.2
