From: Minghao Chi <chi.minghao@xxxxxxxxxx> platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq(). v1->v2: - Use more specific in the subject: ata: pata_pxa: - Switch to returning 'irq' Reported-by: Zeal Robot <zealci@xxxxxxxxxx> Signed-off-by: Minghao Chi <chi.minghao@xxxxxxxxxx> --- drivers/ata/pata_pxa.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/drivers/ata/pata_pxa.c b/drivers/ata/pata_pxa.c index 41430f79663c..340b274d0cad 100644 --- a/drivers/ata/pata_pxa.c +++ b/drivers/ata/pata_pxa.c @@ -164,10 +164,10 @@ static int pxa_ata_probe(struct platform_device *pdev) struct resource *cmd_res; struct resource *ctl_res; struct resource *dma_res; - struct resource *irq_res; struct pata_pxa_pdata *pdata = dev_get_platdata(&pdev->dev); struct dma_slave_config config; int ret = 0; + int irq; /* * Resource validation, three resources are needed: @@ -205,9 +205,9 @@ static int pxa_ata_probe(struct platform_device *pdev) /* * IRQ pin */ - irq_res = platform_get_resource(pdev, IORESOURCE_IRQ, 0); - if (unlikely(irq_res == NULL)) - return -EINVAL; + irq = platform_get_irq(pdev, 0); + if (unlikely(irq < 0)) + return irq; /* * Allocate the host @@ -287,7 +287,7 @@ static int pxa_ata_probe(struct platform_device *pdev) /* * Activate the ATA host */ - ret = ata_host_activate(host, irq_res->start, ata_sff_interrupt, + ret = ata_host_activate(host, irq, ata_sff_interrupt, pdata->irq_flags, &pxa_ata_sht); if (ret) dma_release_channel(data->dma_chan); -- 2.25.1
