From 441617672810482b1f92878b7f82a56cd4f0fcf6 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 13 May 2014 10:26:01 +0300 Subject: [PATCH] ARM: edma: Clean up and simplify the code around irq request Get the two interrupt line number at the same time by merging the two instance of if(node){}else{} places. replace the &pdev->dev with the already existing dev which makes it possible to collapse lines with devm_request_irq() Signed-off-by: Peter Ujfalusi Signed-off-by: Sekhar Nori --- arch/arm/common/edma.c | 26 ++++++++++++-------------- 1 file changed, 12 insertions(+), 14 deletions(-) diff --git a/arch/arm/common/edma.c b/arch/arm/common/edma.c index 25fa735abc6c..b9bd42ad2d6e 100644 --- a/arch/arm/common/edma.c +++ b/arch/arm/common/edma.c @@ -1598,7 +1598,6 @@ static int edma_probe(struct platform_device *pdev) struct resource *r[EDMA_MAX_CC] = {NULL}; struct resource res[EDMA_MAX_CC]; char res_name[10]; - char irq_name[10]; struct device_node *node = pdev->dev.of_node; struct device *dev = &pdev->dev; int ret; @@ -1720,14 +1719,21 @@ static int edma_probe(struct platform_device *pdev) if (node) { irq[j] = irq_of_parse_and_map(node, 0); + err_irq[j] = irq_of_parse_and_map(node, 2); } else { + char irq_name[10]; + sprintf(irq_name, "edma%d", j); irq[j] = platform_get_irq_byname(pdev, irq_name); + + sprintf(irq_name, "edma%d_err", j); + err_irq[j] = platform_get_irq_byname(pdev, irq_name); } edma_cc[j]->irq_res_start = irq[j]; - status = devm_request_irq(&pdev->dev, irq[j], - dma_irq_handler, 0, "edma", - &pdev->dev); + edma_cc[j]->irq_res_end = err_irq[j]; + + status = devm_request_irq(dev, irq[j], dma_irq_handler, 0, + "edma", dev); if (status < 0) { dev_dbg(&pdev->dev, "devm_request_irq %d failed --> %d\n", @@ -1735,16 +1741,8 @@ static int edma_probe(struct platform_device *pdev) return status; } - if (node) { - err_irq[j] = irq_of_parse_and_map(node, 2); - } else { - sprintf(irq_name, "edma%d_err", j); - err_irq[j] = platform_get_irq_byname(pdev, irq_name); - } - edma_cc[j]->irq_res_end = err_irq[j]; - status = devm_request_irq(&pdev->dev, err_irq[j], - dma_ccerr_handler, 0, - "edma_error", &pdev->dev); + status = devm_request_irq(dev, err_irq[j], dma_ccerr_handler, 0, + "edma_error", dev); if (status < 0) { dev_dbg(&pdev->dev, "devm_request_irq %d failed --> %d\n", -- 2.34.1
