When JOYSTICK_ADC is enabled, and IIO_BUFFER is disabled, Kbuild gives the following warning: WARNING: unmet direct dependencies detected for IIO_BUFFER_CB Depends on [n]: IIO [=y] && IIO_BUFFER [=n] Selected by [y]: - JOYSTICK_ADC [=y] && !UML && INPUT [=y] && INPUT_JOYSTICK [=y] && IIO [=y] This is because JOYSTICK_ADC selects IIO_BUFFER_CB without selecting or depending on IIO_BUFFER, despite IIO_BUFFER_CB depending on IIO_BUFFER.
