6.5-stable review patch. If anyone has any objections, please let me know. ------------------ From: Antoniu Miclaus <antoniu.miclaus@xxxxxxxxxx> commit b120dd3a15582fb7a959cecb05e4d9814fcba386 upstream. Building ad74413r without selecting IIO_BUFFER and IIO_TRIGGERED_BUFFER generates error with respect to the iio trigger functions that are used within the driver. Update the Kconfig accordingly.
