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.

Say Y here if you have a simple joystick connected over ADC.
