 211           By default, a media driver auto-selects all possible ancillary
 212           devices such as tuners, sensors, video encoders/decoders and
 213           frontends, that are used by any of the supported devices.
 214
 215           This is generally the right thing to do, except when there
 216           are strict constraints with regards to the kernel size,
 217           like on embedded systems.
 218
 219           Use this option with care, as deselecting ancillary drivers which
 220           are, in fact, necessary will result in the lack of the needed
 221           functionality for your device (it may not tune or may not have
 222           the needed demodulators).
