If a driver does not assign an of_node to a IIO device to IIO core will automatically assign the of_node of the parent device. This automatic assignment is done in the iio_device_register() function. There is a fair amount of drivers that currently manually assign the of_node of the IIO device. All but 4 of them can make use of the automatic assignment though. The exceptions are: * mxs-lradc-adc: Which uses the of_node of the parent of the parent. * stm32-dfsdm-adc, stm32-adc and stm32-dac: Which reference the of_node assigned to the IIO device before iio_device_register() is called. All other drivers are updated to use automatic assignment. This reduces the amount of boilerplate code involved in setting up the IIO device. The patch has mostly been auto-generated with the following semantic patch // <smpl> @exists@ expression indio_dev; expression parent; @@ indio_dev = \(devm_iio_device_alloc\|iio_device_alloc\)(&parent, ...) ... -indio_dev->dev.of_node = parent.of_node; @exists@ expression indio_dev; expression parent; @@ indio_dev = \(devm_iio_device_alloc\|iio_device_alloc\)(parent, ...) ... -indio_dev->dev.of_node = parent->of_node; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> |
