CONFIG_SIMPLE_DUMMY_BUFFER compiles in iio_simple_dummy_buffer.c file which uses functions from industrialio-trigger.c. So, CONFIG_SIMPLE_DUMMY_BUFFER needs to select IIO_TRIGGER in order to avoid build error like this: > ERROR: "iio_trigger_notify_done" [drivers/staging/iio/iio_dummy.ko] undefined! > ERROR: "iio_triggered_buffer_postenable" [drivers/staging/iio/iio_dummy.ko] undefined! > ERROR: "iio_triggered_buffer_predisable" [drivers/staging/iio/iio_dummy.ko] undefined! > ERROR: "iio_alloc_pollfunc" [drivers/staging/iio/iio_dummy.ko] undefined! > ERROR: "iio_dealloc_pollfunc" [drivers/staging/iio/iio_dummy.ko] undefined!
