From c5d98b6400263309b9208a63ee3d273f730ef80f Mon Sep 17 00:00:00 2001 From: Jun Nie Date: Tue, 10 Jan 2017 17:23:40 +0800 Subject: [PATCH] dmaengine: zx: fix build warning commit 067fdeb2f391bfa071f741a2b3eb74b8ff3785cd upstream. Fix build warning that related to PAGE_SIZE. The maximum DMA length has nothing to do with PAGE_SIZE, just use a fix number for the definition. drivers/dma/zx_dma.c: In function 'zx_dma_prep_memcpy': drivers/dma/zx_dma.c:523:8: warning: division by zero [-Wdiv-by-zero] drivers/dma/zx_dma.c: In function 'zx_dma_prep_slave_sg': drivers/dma/zx_dma.c:567:11: warning: division by zero [-Wdiv-by-zero] Signed-off-by: Jun Nie Tested-by: Shawn Guo Signed-off-by: Vinod Koul Signed-off-by: Greg Kroah-Hartman --- drivers/dma/zx296702_dma.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/dma/zx296702_dma.c b/drivers/dma/zx296702_dma.c index 6059d81e701a..8e55403847b2 100644 --- a/drivers/dma/zx296702_dma.c +++ b/drivers/dma/zx296702_dma.c @@ -26,7 +26,7 @@ #define DRIVER_NAME "zx-dma" #define DMA_ALIGN 4 -#define DMA_MAX_SIZE (0x10000 - PAGE_SIZE) +#define DMA_MAX_SIZE (0x10000 - 512) #define LLI_BLOCK_SIZE (4 * PAGE_SIZE) #define REG_ZX_SRC_ADDR 0x00
