 216           By default, a media driver auto-selects all possible ancillary
 217           devices such as tuners, sensors, video encoders/decoders and
 218           frontends, that are used by any of the supported devices.
 219
 220           This is generally the right thing to do, except when there
 221           are strict constraints with regards to the kernel size,
 222           like on embedded systems.
 223
 224           Use this option with care, as deselecting ancillary drivers which
 225           are, in fact, necessary will result in the lack of the needed
 226           functionality for your device (it may not tune or may not have
 227           the needed demodulators).
