From: Randy Dunlap <rdunlap@infradead.org>
The dln2-adc driver uses interface(s) that are controlled by the IIO_TRIGGERED_BUFFER Kconfig symbol, so the driver needs to select that symbol to prevent the build error.
drivers/iio/adc/dln2-adc.o: In function `dln2_adc_probe': dln2-adc.c:(.text+0x528): undefined reference to `devm_iio_triggered_buffer_setup'
