 205           By default, a media driver auto-selects all possible ancillary
 206           devices such as tuners, sensors, video encoders/decoders and
 207           frontends, that are used by any of the supported devices.
 208
 209           This is generally the right thing to do, except when there
 210           are strict constraints with regards to the kernel size,
 211           like on embedded systems.
 212
 213           Use this option with care, as deselecting ancillary drivers which
 214           are, in fact, necessary will result in the lack of the needed
 215           functionality for your device (it may not tune or may not have
 216           the needed demodulators).
