+static int mx25_tsadc_setup_irq(struct platform_device *pdev, + struct mx25_tsadc *tsadc) +{ + struct device *dev = &pdev->dev; + struct device_node *np = dev->of_node; + int irq; + + irq = platform_get_irq(pdev, 0); + if (irq < 0) {What if 0 is returned?Then imx25.dtsi would be passing irq=0 for the ADC, which would be totally wrong.Exactly, so it should be <=.
imx25.dtsi passes interrupts = <46>; for the touch screen controller, so the irq number will never be zero.
