It is there to give it it a presence in the device model.

The dev isn't the underlying device (e.g. the spi one or i2c one but rather one created by the iio subsystem to give the iio_dev a presence in the device model - on the iio sysfs bus). > + * @attr: Pointer to the device_attribute structure that > + * is being processed > + * @buf: Buffer where the current trigger name will be printed into > * > * For trigger consumers the current_trigger interface allows the trigger > * used by the device to be queried. > - **/ > + * > + * Return: a negative number on failure, the number of characters written > + * on success or 0 if no trigger is available > + */ > static ssize_t iio_trigger_read_current(struct device *dev, > struct device_attribute *attr, > char *buf) > @@ -305,11 +319,18 @@ static ssize_t iio_trigger_read_current(struct device *dev, > > /** > * iio_trigger_write_current() - trigger consumer sysfs set current trigger > + * @dev: Device that this iio_dev belongs to > + * @attr: Device attribute that is being processed > + * @buf: String buffer that holds the name of the trigger > + * @len: Length of the trigger name held by buf > * > * For trigger consumers the current_trigger interface allows the trigger > * used for this device to be specified at run time based on the trigger's > * name. > - **/ > + * > + * Return: negative error code on failure or length of the buffer > + * on success > + */ > static ssize_t iio_trigger_write_current(struct device *dev, > struct device_attribute *attr, > const char *buf, > -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
