From b7862742feadf22cc1496bb6b460236a900512db Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Wed, 21 Sep 2016 15:41:28 +0300 Subject: [PATCH] dmaengine: edma: Fix of_device_id data parameter usage (legacy vs TPCC) Use pointers to static constant variables for eDMA binding type (legacy vs TPCC). Fixes the following warning when compiling the driver for 64bit architectures (x86_64 for example): drivers/dma/edma.c:2185:16: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] if (match && (u32)match->data == EDMA_BINDING_TPCC) ^ Signed-off-by: Peter Ujfalusi Signed-off-by: Vinod Koul --- drivers/dma/edma.c | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) diff --git a/drivers/dma/edma.c b/drivers/dma/edma.c index c2098a4b4dcf..951b8b204a47 100644 --- a/drivers/dma/edma.c +++ b/drivers/dma/edma.c @@ -263,14 +263,19 @@ static const struct edmacc_param dummy_paramset = { #define EDMA_BINDING_LEGACY 0 #define EDMA_BINDING_TPCC 1 +static const u32 edma_binding_type[] = { + [EDMA_BINDING_LEGACY] = EDMA_BINDING_LEGACY, + [EDMA_BINDING_TPCC] = EDMA_BINDING_TPCC, +}; + static const struct of_device_id edma_of_ids[] = { { .compatible = "ti,edma3", - .data = (void *)EDMA_BINDING_LEGACY, + .data = &edma_binding_type[EDMA_BINDING_LEGACY], }, { .compatible = "ti,edma3-tpcc", - .data = (void *)EDMA_BINDING_TPCC, + .data = &edma_binding_type[EDMA_BINDING_TPCC], }, {} }; @@ -2184,7 +2189,7 @@ static int edma_probe(struct platform_device *pdev) const struct of_device_id *match; match = of_match_node(edma_of_ids, node); - if (match && (u32)match->data == EDMA_BINDING_TPCC) + if (match && (*(u32 *)match->data) == EDMA_BINDING_TPCC) legacy_mode = false; info = edma_setup_info_from_dt(dev, legacy_mode); -- 2.39.2
