iio:trigger: Introduce iio_tigger_{set,get}_drvdata
Introduce iio_tigger_{set,get}_drvdata which allows to attach driver specific data to a trigger. The functions wrap access to the triggers private_data field and all current users are updated to use iio_tigger_{set,get}_drvdata instead of directly accessing the private_data field. This is the first step towards removing the private_data field from the iio_trigger struct. The following coccinelle script has been used to update the drivers: <smpl> @@ struct iio_trigger *trigger; expression priv; @@ -trigger->private_data = priv +iio_trigger_set_drv_data(trigger, priv) @@ struct iio_trigger *trigger; @@ -trigger->private_data +iio_trigger_get_drv_data(trigger) </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
