From 8cb631ccbb1952b6422917f2ed16f760d84a762e Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sat, 13 Jun 2020 14:17:15 +0200 Subject: iio: Remove superfluous of_node assignments 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 // @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; // Signed-off-by: Lars-Peter Clausen Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron --- drivers/iio/dac/ti-dac5571.c | 1 - 1 file changed, 1 deletion(-) (limited to 'drivers/iio/dac/ti-dac5571.c') diff --git a/drivers/iio/dac/ti-dac5571.c b/drivers/iio/dac/ti-dac5571.c index 502552716e1e..f08c0a859ad4 100644 --- a/drivers/iio/dac/ti-dac5571.c +++ b/drivers/iio/dac/ti-dac5571.c @@ -321,7 +321,6 @@ static int dac5571_probe(struct i2c_client *client, i2c_set_clientdata(client, indio_dev); data->client = client; - indio_dev->dev.of_node = client->dev.of_node; indio_dev->info = &dac5571_info; indio_dev->name = id->name; indio_dev->modes = INDIO_DIRECT_MODE; -- cgit
