Building the at91 adc driver with CONFIG_INPUT disabled results in this build error: ERROR: "input_event" [drivers/iio/adc/at91_adc.ko] undefined! ERROR: "input_unregister_device" [drivers/iio/adc/at91_adc.ko] undefined! ERROR: "input_free_device" [drivers/iio/adc/at91_adc.ko] undefined! ERROR: "input_register_device" [drivers/iio/adc/at91_adc.ko] undefined! ERROR: "input_set_abs_params" [drivers/iio/adc/at91_adc.ko] undefined! ERROR: "input_allocate_device" [drivers/iio/adc/at91_adc.ko] undefined! To make sure we can build random configurations, this turns on CONFIG_INPUT whenever CONFIG_AT91_ADC is enabled.
