Switch case figures out the type of irq and if it's the default case then assign the default value to the irq_type i.e. irq_type = IRQF_TRIGGER_LOW Signed-off-by: Shreeya Patel --- drivers/staging/iio/addac/adt7316.c | 21 +++++++++++++++++---- 1 file changed, 17 insertions(+), 4 deletions(-) diff --git a/drivers/staging/iio/addac/adt7316.c b/drivers/staging/iio/addac/adt7316.c index 9c72538baf9e..c647875a64f5 100644 --- a/drivers/staging/iio/addac/adt7316.c +++ b/drivers/staging/iio/addac/adt7316.c @@ -2101,8 +2101,7 @@ int adt7316_probe(struct device *dev, struct adt7316_bus *bus, { struct adt7316_chip_info *chip; struct iio_dev *indio_dev; - unsigned short *adt7316_platform_data = dev->platform_data; - int irq_type = IRQF_TRIGGER_LOW; + int irq_type; int ret = 0; indio_dev = devm_iio_device_alloc(dev, sizeof(*chip)); @@ -2146,8 +2145,22 @@ int adt7316_probe(struct device *dev, struct adt7316_bus *bus, indio_dev->modes = INDIO_DIRECT_MODE; if (chip->bus.irq > 0) { - if (adt7316_platform_data[0]) - irq_type = adt7316_platform_data[0]; + irq_type = + irqd_get_trigger_type(irq_get_irq_data(chip->bus.irq)); + + switch (irq_type) { + case IRQF_TRIGGER_HIGH: + case IRQF_TRIGGER_RISING: + break; + case IRQF_TRIGGER_LOW: + case IRQF_TRIGGER_FALLING: + break; + default: + dev_info(dev, "mode %d unsupported, using IRQF_TRIGGER_LOW\n", + irq_type); + irq_type = IRQF_TRIGGER_LOW; + break; + } ret = devm_request_threaded_irq(dev, chip->bus.irq, NULL,
